molecular cloning a laboratory manual freeNo other manual has been so popular, or so influential. Molecular Cloning, Fourth Edition, by the celebrated founding author Joe Sambrook and new co-author, the distinguished HHMI investigator Michael Green, preserves the highly praised detail and clarity of previous editions and includes specific chapters and protocols commissioned for the book from expert practitioners at Yale, U Mass, Rockefeller University, Texas Tech, Cold Spring Harbor Laboratory, Washington University, and other leading institutions. The theoretical and historical underpinnings of techniques are prominent features of the presentation throughout, information that does much to help trouble-shoot experimental problems. For the fourth edition of this classic work, the content has been entirely recast to include nucleic-acid based methods selected as the most widely used and valuable in molecular and cellular biology laboratories. Core chapters from the third edition have been revised to feature current strategies and approaches to the preparation and cloning of nucleic acids, gene transfer, and expression analysis. They are augmented by 12 new chapters which show how DNA, RNA, and proteins should be prepared, evaluated, and manipulated, and how data generation and analysis can be handled. The new content includes methods for studying interactions between cellular components, such as microarrays, next-generation sequencing technologies, RNA interference, and epigenetic analysis using DNA methylation techniques and chromatin immunoprecipitation. To make sense of the wealth of data produced by these techniques, a bioinformatics chapter describes the use of analytical tools for comparing sequences of genes and proteins and identifying common expression patterns among sets of genes. It has a pure-bred ancestry, and the new edition does not disappoint. (It) includes information panels at the end of each chapter that describe the principles behind the protocols.http://hk4tutor.com/upload/canon-ws-1400h-manual.xml

These features are just a taste of more than thirty works produced for the conference, and readers are invited to read the full selection here. Enjoy! Within this long history, the invention of recombinant DNA techniques in the early 1970s proved to be especially pivotal. The ability to manipulate DNA consolidated the high-profile focus on molecular genetics, a trend underway since Watson and Crick’s double-helical model in 1953. But the ramifications of this technology extended far beyond investigating heredity itself. Biologists doing research on a wide variety of molecules, including enzymes, hormones, muscle proteins, RNAs, as well as chromosomal DNA, could harness genetic engineering to copy the gene that encoded their molecule of interest, from whatever organism they worked on, and put that copy in a bacterial cell, from which it might be expressed, purified, and characterized. Many life scientists who wanted to use recombinant DNA techniques were not trained in molecular biology. They sought technical know-how on their own in order to bring their labs into the vanguard of gene cloners. Manuals became a key part of this dissemination of expertise. Simply put, cloning is copying, and a gene is usually copied onto a vector that can replicate in a cell, so that the copied gene can be propagated and studied. In seeking to make copies of genes and move them around from organism to organism, biologists were inspired by bacteria, whose ability to exchange genetic material had been recognized in 1946 by Joshua Lederberg and Edward Tatum. It turned out that there were numerous genetic units that enabled gene exchange in bacteria, including lysogenic viruses and fertility factors. In 1952 Lederberg christened the entities “plasmids.”. The discovery of bacterial restriction enzymes, which sever DNA strands at specific base-pair combinations, inspired molecular biologists to attempt to use these as microscopic scissors. In principle, if a researcher could identify and locate a particular eukaryotic gene, she could use a restriction enzyme to “cut” it out of chromosomal DNA and insert it into a circular bacterial plasmid (Figure 1). Cloning eukaryotic genes was an immensely difficult task, and several early attempts faltered. Other efforts did not go forward due to the potential public health hazards of placing genes from widely-studied tumor viruses into E. coli, a bacterium that usually inhabits the gut of humans. No one knew whether exposure to bacteria toting these tumor-associated genes could give people cancer. Not only was the inserted gene on its plasmid vector taken up and replicated by E. coli, but also the foreign DNA was expressed into the corresponding product RNA. Their 1974 publication became the much-cited proof that genes from a higher organism could be cloned and expressed in a bacterium. Richard Roberts at Cold Spring Harbor discovered and purified many of the restriction enzymes essential for this work. He recalls that “Summer visitors would stop by with a tube of their favorite DNA in their pocket, just to see if we had an enzyme that would convert it into some useful fragments.” Unable to persuade his own institution to start manufacturing and selling restriction enzymes, Roberts helped the newly-founded New England Biolabs corner this market. The first company catalog was issued in 1975; their enzymes became indispensable to the early gene cloners. Biologists who worked on bacteria were able to rapidly exploit these newly commercialized enzymes and customized plasmids, so that the cloning of genes from microbes took off. Simply obtaining genetic material from higher organisms in a form that could be searched for a specific gene was a formidable challenge. Courses (for practitioners, not only university students) became a popular way to meet this demand. One popular course, “Advanced Bacterial Genetics,” already offered researchers a chance to learn how to identify, map, and copy genes from prokaryotes. In 1980, Cold Spring Harbor Laboratory (CSHL) began offering a postgraduate summer course called “Molecular Cloning of Eukaryotic Genes.” James Watson, director of CSHL, asked Maniatis to teach this course, and others joined the effort. Nancy Hopkins, who had taught a tumor virology course that had just ended, stayed on for the cloning course. Only sixteen students could enroll. Watson immediately saw the opportunity to make cloning know-how available to a wider base of users through publication. Issuing an instructional guide from Cold Spring Harbor Laboratory would further consolidate the institution’s reputation for being at the vanguard of molecular biology—and there was already a tradition there of publishing course manuals as books. Author photo. But he had recently moved to Caltech, where he was busy chairing an NIH study section and running his own lab. Maniatis handed off teaching of the “Molecular Cloning of Eukaryotic Genes” summer course at CSHL to others the same year as the manual came out. One can see how the book is spiral bound so it lays flat when open. Author photo. There were orders for more than 5000 copies before the publication date. Consequently, the press sold 5113 copies the first month of its appearance, in July 1982 (as compared with its original number for sales projected by the press: 210 copies). In August 988 copies were sold, in September 2487, in October 1863, and in November 768. As a reviewer in Nature put it, For the most part, such laboratory methods fall far short of this goal. So why the excitement surrounding the long-awaited second edition of the classic guide, Molecular Cloning, which first appeared in 1982. The original version immediately filled the need for an anthology of laboratory procedures pertinent to the emerging field of recombinant DNA. Author photo. Rather than being written by three authors, this manual was produced by an entire team of scientists, who contributed individual pieces on various techniques. In addition, Current Protocols had a very different way of dealing with the rapid growth (and obsolescence) of techniques—the book was designed to be expanded via subscription. Through a quarterly update service, subscribers received supplements to insert into the original loose-leaf binder, which was separated into sections by preprinted dividers (Figures 4 and 5). This meant that the Table of Contents also needed frequent updating. Five thick binders were published in the original series (Figure 6). Author photo. This single volume work was bound as a traditional text, with wide pages in a format that would prop open easily on the back of a lab bench. The challenge of updating was more easily accommodated by the growth of multimedia technologies in the 1990s. The 2001 edition came with a CD-ROM “Lab Book.” By the third edition (2001), Molecular Cloning: A Laboratory Manual also had an associated website for its publication. Moving manuals online put knowledge at one’s fingertips in a new way, yet the demand for guides that can be plopped open on a lab bench has meant that print versions retain value, as evidenced by the publication of a fourth edition of Molecular Cloning in 2012. Most fields of life science today, including bioinformatics, cell biology, immunology, neuroscience, stem cell science, and toxicology, have their go-to manuals and protocol books, in print and online. Author photo. Their ubiquity enriches our understanding of the scientific process. An obsession with innovation may blind us to the importance of procedure, repeatability, and tried-and-true methods. Manuals make discovery possible, by leading scientists through the routine steps of their experiments and (if the manual is good) helping them trouble-shoot when experiments fail. In a world of hyper-specialized research, guide books are bridges, carrying technical know-how between laboratories and enabling researchers to master the latest methods without going back to school. Involving him as an author of the molecular cloning manual enabled a certain redress at CSHL. A few years earlier Sambrook had contributed significantly to John Tooze’s Tumor Virology book, but this was not acknowledged by his being an author. Personal communication, Alex Gann, 26 May 2010. At that meeting Molecular Cloning sold 83 copies, and all the other sales together, 22 titles in all, made up 102 copies. This edition was three volumes. Tweet or email links to related discussions.

In mammalian cell lines reassociation kinetics experiments indicate the expression of 10,000 to 30,000 genes (Sambrook and Russell, 2001 ). Brain cells express as many as 100,000 genes (Bantle and Hahn, 1976)... Probably these are overestimates since genome sequencing reveals only 30,000 genes in humans, 14,000 in the fly and 20,000 in the worm (Levine and Tjian, 2003). Currently, it is believed that 20 of the cell mRNA population is composed of abundant transcripts (12,000 to 1,000 copies per cell), 25 of medium abundance mRNA (1,000 to 100 copies per cell) and the remaining 50 consists of low abundance transcripts (Sambrook and Russell, 2001). But, how many of those are specific?.. The protocols used are standard molecular biology protocols, commonly used and performed according to Sambrook and Russell (2001). The methods described below were necessary for the execution of a differential hybridisation screen on macroarray ventral midgut cDNA library filters.. Endodermal Patterning in Xenopus laevis Thesis Jun 2004 The endoderm is the inner germ layer of the vertebrate embryo from which the respiratory and digestive systems are derived. These include organs such as the liver, pancreas, stomach, lungs and intestine. Recent research has helped our understanding of early vertebrate endoderm specification and terminal differentiation of specific endodermal lineages. However, very little is known about the molecular mechanisms that control endoderm patterning and morphogenesis during vertebrate development. Here, I report the identification and characterisation of a dozen novel regionally expressed endoderm genes. At tailbud stages their expression patterns fall into three re-occurring domains, anterior ventral midgut endoderm, posterior endoderm and dorsal endoderm. In addition, regional expression of some of these genes is observable at gastrula stages, during endoderm specification. These are the first early stable endodermal markers for different regions of the gastrula endoderm. This suggests that the earliest steps in endoderm patterning are concurrent with endoderm specification. I present an overview of endoderm development together with the results from my screen. Overall, these results reveal an unexpected degree of early endodermal patterning and assist our understanding of the link between early and late events of vertebrate endoderm development. In addition, this work provides us with new and very useful markers for the study of endodermal patterning, but also perhaps some key developmental regulators of endodermal formation.

Reintroduction of colistin as last resort treatment in the infections caused by drug-resistant Gram-negative bacteria has led to the emergence and spread of colistin resistance. This study was designed to determine the prevalence of drug-resistance among beta-lactamase-producing strains of Escherichia coli and Klebsiella pneumoniae, isolated from the clinical specimens received at a tertiary care centre of Kathmandu, Nepal during the period of March to August, 2019. Methods. A total of 3216 different clinical samples were processed in the Microbiology laboratory of Kathmandu Model Hospital. Gram-negative isolates ( E. coli and K. pneumoniae ) were processed for antimicrobial susceptibility test (AST) by using modified Kirby-Bauer disc diffusion method. Drug-resistant isolates were further screened for extended-spectrum beta-lactamase (ESBL), metallo-beta-lactamase (MBL), carbapenemase and K. pneumoniae carbapenemase (KPC) production tests. All the suspected enzyme producers were processed for phenotypic confirmatory tests. Colistin resistance was determined by minimum inhibitory concentration (MIC) using agar dilution method. Colistin resistant strains were further screened for plasmid-mediated mcr-1 gene using conventional polymerase chain reaction (PCR). Results. A total of 583 bacterial isolates were recovered from 529 clinical samples. In AST, colistin, polymyxin B and tigecycline were the most effective antibiotics. Conclusion. High prevalence of drug-resistance in our study is indicative of a deteriorating situation of AMR. Moreover, significant prevalence of resistant enzymes in our study reinforces their roles in the emergence of drug resistance. Resistance to last resort drug (colistin) and the isolation of mcr-1 indicate further urgency in infection management. Therefore, extensive surveillance, formulation and implementation of effective policies, augmentation of diagnostic facilities and incorporation of antibiotic stewardship programs can be some remedies to cope with this global crisis.

Accordingly, 616-bp and 1028-bp amplicons of pObCVOMT and pObEOMT were puri ed using the glassmilk method (Sambrook and Russell, 2001 ), ligated to a pTG19-T PCR cloning vector (Vivantis, Korea) and chemically transformed in competent DH5.Finally, the extracted plasmid was used to determine the sequence (Bioneer Biotechnology Co. These vectors were subsequently moved into Agrobacterium tumefaciens (strain C58) according to the method described by. Identification and Functional Characterization of the CVOMT and EOMT Genes Promoters from Ocimum Basilicum L Preprint Full-text available Jun 2021 Fatemeh Khakdan Zahra Shirazi Mojtaba Ranjbar Methyl chavicol and methyl eugenol are important phenylpropanoid compounds previously purified from basil. These compounds are significantly enhanced by the water deficit stress-dependent mechanism. Here, for the first time, pObCVOMT and pObEOMT promoters were extracted by the genome walking method. They were then cloned into the upstream of the ?-glucuronidase ( GUS ) reporter gene to identify the pattern of GUS water deficit stress-specific expression. Histochemical GUS assays showed in transgenic tobacco lines bearing the GUS gene driven by pObCVOMT and pObEOMT promoters, GUS was strongly expressed under water deficit stress.This indicates these promoters are able to drive inducible expression. The cis -acting elements analysis showed that the pObCVOMT and pObEOMT promoters contained dehydration or water deficit-related transcriptional control elements. Minipreparation of plasmid DNAs from bacterial colonies were performed as previously described (45) with minor modification. Cell samples were used for extracting plasmid DNAs, following the previous protocol (45), with the plasmid DNAs analyzed by agarose gel electrophoresis. We found, in the stepwise induction of LdCsm effector and CTR, massive DNA degradation occurred already at 30 min after CTR synthesis (CTR in L-arabinose, Figure 5C), which was in strict contrast to the preferred degradation of nontarget plasmid observed with the simultaneously induction of both LdCsm and CTR (CTR in L-arabinose, Figure 5B).. A type III-A CRISPR-Cas system mediates co-transcriptional DNA cleavage at the transcriptional bubbles in close proximity to active effectors Article Full-text available Jul 2021 Nucleic Acids Res Jinzhong Lin Yulong Shen Jinfeng Ni Qunxin She Many type III CRISPR-Cas systems rely on the cyclic oligoadenylate (cOA) signaling pathway to exert immunization. However, LdCsm, a type III-A lactobacilli immune system mediates efficient plasmid clearance in spite of lacking cOA signaling. Thus, the system provides a good model for detailed characterization of the RNA-activated DNase in vitro and in vivo. We found ATP functions as a ligand to enhance the LdCsm ssDNase, and the ATP enhancement is essential for in vivo plasmid clearance. In vitro assays demonstrated LdCsm cleaved transcriptional bubbles at any positions in non-template strand, suggesting that DNA cleavage may occur for transcribing DNA. Destiny of target plasmid versus nontarget plasmid in Escherichia coli cells was investigated, and this revealed that the LdCsm effectors mediated co-transcriptional DNA cleavage to both target and nontarget plasmids, suggesting LdCsm effectors can mediate DNA cleavage to any transcriptional bubbles in close proximity upon activation. Subcellular locations of active LdCsm effectors were then manipulated by differential expression of LdCsm and CTR, and the data supported the hypothesis. Strikingly, stepwise induction experiments indicated allowing diffusion of LdCsm effector led to massive chromosomal DNA degradation, suggesting this unique IIIA system can facilitate infection abortion to eliminate virus-infected cells. Indigenous microbes from dumpsite soil samples were isolated and identified based on 16S rRNA sequencing and phylogenetic analysis. All the dumpsite samples showed bioavailability for POPs and PAHs. The fungal cell wall is an essential and robust external structure that protects the cell from the environment. It is mainly composed of polysaccharides with different functions, some of which are necessary for cell integrity. Thus, the process of fractionation and analysis of cell wall polysaccharides is useful for studying the function and relevance of each polysaccharide, as well as for developing a variety of practical and commercial applications. This method can be used to study the mechanisms that regulate cell morphogenesis and integrity, giving rise to information that could be applied in the design of new antifungal drugs. Nonetheless, for this method to be reliable, the availability of trustworthy commercial recombinant cell wall degrading enzymes with non-contaminating activities is vital. Here we examined the efficiency and reproducibility of 12 recombinant endo-?(1,3)- d -glucanases for specifically degrading the cell wall ?(1,3)- d -glucan by using a fast and reliable protocol of fractionation and analysis of the fission yeast cell wall. The cell wall degradation caused by PfLam16A was similar to that of Quantazyme, a recombinant endo-?(1,3)- d -glucanase no longer commercially available. Moreover, other recombinant ?(1,3)- d -glucanases caused either incomplete or excessive degradation, suggesting deficient access to the substrate or release of other polysaccharides. Conclusions. The discovery of a reliable and efficient recombinant endo-?(1,3)- d -glucanase, capable of replacing the previously mentioned enzyme, will be useful for carrying out studies requiring the digestion of the fungal cell wall ?(1,3)- d -glucan. This new commercial endo-?(1,3)- d -glucanase will allow the study of the cell wall composition under different conditions, along the cell cycle, in response to environmental changes or in cell wall mutants.
