Book excerpt: Peptides are important affinity ligands for microscopy, biosensing, and targeted delivery. However, because they can have low affinity for their targets, their selection from large naïve libraries can be challenging. When selecting peptidic ligands from display libraries, it is important to: 1) ensure efficient display; 2) maximize the ability to select high affinity ligands; and 3) minimize the effect of the display context on binding. The "helper cell" packaging system has been described as a tool to produce filamentous phage particles based on phagemid constructs with varying display levels, while remaining free of helper phage contamination. Here we report on the first use of this system for peptide display, including the systematic characterization and optimization of helper cells, their inefficient use in antibody display and their use in creating and selecting from a set of phage display peptide libraries. Our libraries were analyzed with unprecedented precision by standard or deep sequencing, and shown to be superior in quality than commercial gold standards. Using our helper cell libraries, we have obtained ligands recognizing Yersinia pestis surface antigen F1V and L-glutamine-binding periplasmic protein QBP. In the latter case, unlike any of the peptide library selections described so far, we used a combination of phage and yeast display to select intriguing peptide ligands. Here, based on the success of our selections we believe that peptide libraries obtained with helper cells are not only suitable, but preferable to traditional phage display libraries for selection of peptidic ligands.

Available in PDF, EPUB and Kindle. Book excerpt: Phage display has become established as a powerful protein engineering method for identifying polypeptides with novel properties, and altering the properties of existing ones. Although the technique is widely used in biological research and drug discovery, it remains technically challenging, and new applications and procedures continue to evolve. Phage Display - A Practical Approach is an up-to-date, comprehensive and integrated experimental guide to the technique, useful for novice and expert alike. The book aims to enable researchers to design and undertake all aspects of a phage display project, from designing an experimental strategy and constructing a library to performing selections and analyzing the results. An introductory chapter provides an overview of phage biology and phage display, including guidelines for planning a successful phage display experiment. Individual chapters provide protocols for constructing libraries using oligonucleotide-directed mutagenesis or DNA recombination, performing binding selections, and analyzing the binding activities of selected phage clones. Separate chapters then cover common applications, including selection of ligands from peptide libraries, generation of phage antibody libraries and isolation and optimization of antibodies, selection of DNA binding proteins, and expression cloning using cDNA display. Further chapters describe alternative selection strategies, such as selection using immune sera, selection based on enzymatic activity or protein stability, and selection in vivo. Protocols and chapters are extensively cross-referenced, allowing readers to move beyond the specific examples given to customize the procedures to their own protein or selection system of interest. Written by experts in the field, Phage Display - A Practical Approach provides a comprehensive guide to the design and execution of phage display projects, for all those using the technique in basic research and drug discovery.

Download or read book Phage Display written by Carlos F. Barbas and published by CSHL Press. This book was released on 2001 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phage-display technology has begun to make critical contributions to the study of molecular recognition. DNA sequences are cloned into phage, which then present on their surface the proteins encoded by the DNA. Individual phage are rescued through interaction of the displayed protein with a ligand, and the specific phage is amplified by infection of bacteria. Phage-display technology is powerful but challenging and the aim of this manual is to provide comprehensive instruction in its theoretical and applied so that any scientist with even modest molecular biology experience can effectively employ it. The manual reflects nearly a decade of experience with students of greatly varying technical expertise andexperience who attended a course on the technology at Cold Spring Harbor Laboratory. Phage-display technology is growing in importance and power. This manual is an unrivalled source of expertise in its execution and application.

Book Synopsis Antibody Phage Display by : Philippa M. O’Brien
Download or read book Antibody Phage Display written by Philippa M. O’Brien and published by Springer Science & Business Media. This book was released on 2008-02-05 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: The closing years of the 19th century and the start of the 20th century witnessed the emergence of microbiology and immunology as discrete sci- tific disciplines, and in the work of Roux and Yersin, perhaps the first benefits of their synergy—immunotherapy against bacterial infection. As we advance into the new millennium, microbiology and immunology again offer a c- ceptual leap forward as antibody phage display gains increasing acceptance as the definitive technology for monoclonal production and unleashes new - portunities in immunotherapy, drug discovery, and functional genomics. In assembling Antibody Phage Display: Methods and Protocols, we have aimed to produce a resource of real value for scientists who have followed the development of phage display technology over the past decade. The founding principles of phage display have always held an elegant simplicity. We hope that readers will find similar clarity in the technical guidance offered by the book’s contributors. In meeting our objectives, we have tried to cover the broad scope of the technology and the key areas of library construction, scre- ing, antibody modification, and expression. Of course, the technology cont- ues to advance apace, but we trust that readers will be able to gage the potential of phage display from our coverage, that some of its subtleties will emerge, and that our selection of methods will prove appealing. We are indebted to all the contributing authors for sharing their expertise with the wider scientific community.
Book Synopsis Biocommunication of Phages by : Guenther Witzany
Download or read book Biocommunication of Phages written by Guenther Witzany and published by Springer Nature. This book was released on 2020-06-29 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to systemize all levels of communicative behavior of phages. Phages represent the most diverse inhabitants on this planet. Until today they are completely underestimated in their number, skills and competences and still remain the dark matter of biology. Phages have serious effects on global energy and nutrient cycles. Phages actively compete for host. They can distinguish between ‘self’ and ‘non-self’ (complement same, preclude others). They process and evaluate available information and then modify their behaviour accordingly. These diverse competences show us that this capacity to evaluate information is possible owing to communication processes within phages (intra-organismic), between the same, related and different phage species (interorganismic), and between phages and non-phage organisms (transorganismic). This is crucial in coordinating infection strategies (lytic vs. lysogenic) and recombination in phage genomes. In 22 chapters, expert contributors review current research into the varying forms of phage biocommunication and Phagetherapy. Biocommunication of Phages aims to assess the current state of research, to orient further investigations on how phages communicate with each other to coordinate their behavioral patterns, and to inspire further investigation of the role of non-phage viruses (non-lytic, non-prokaryotic) in these highly dynamic interactional networks.

Download or read book The Perfect Predator written by Steffanie Strathdee and published by Hachette Books. This book was released on 2019-02-26 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: An electrifying memoir of one woman's extraordinary effort to save her husband's life-and the discovery of a forgotten cure that has the potential to save millions more. "A memoir that reads like a thriller." -New York Times Book Review "A fascinating and terrifying peek into the devastating outcomes of antibiotic misuse-and what happens when standard health care falls short." -Scientific American Epidemiologist Steffanie Strathdee and her husband, psychologist Tom Patterson, were vacationing in Egypt when Tom came down with a stomach bug. What at first seemed like a case of food poisoning quickly turned critical, and by the time Tom had been transferred via emergency medevac to the world-class medical center at UC San Diego, where both he and Steffanie worked, blood work revealed why modern medicine was failing: Tom was fighting one of the most dangerous, antibiotic-resistant bacteria in the world. Frantic, Steffanie combed through research old and new and came across phage therapy: the idea that the right virus, aka "the perfect predator," can kill even the most lethal bacteria. Phage treatment had fallen out of favor almost 100 years ago, after antibiotic use went mainstream. Now, with time running out, Steffanie appealed to phage researchers all over the world for help. She found allies at the FDA, researchers from Texas A&M, and a clandestine Navy biomedical center -- and together they resurrected a forgotten cure. A nail-biting medical mystery, The Perfect Predator is a story of love and survival against all odds, and the (re)discovery of a powerful new weapon in the global superbug crisis.
