Methods in Biotechnology – serie

This authoritative collection of basic and advanced protocols permits biotechnologists to use plants rather than single cell fermentation systems for expressing recombinant proteins. The protocols provide clear step-by-step instructions for the cloning, expression, and analysis of a wide variety of recombinant proteins in plants, and for the cloning of genes into a number of different plant species. The book also describes promising experimental techniques that will become increasingly important in the future, and includes techniques for the characterization of medically important proteins expressed in plants.

A cutting-edge collection of detailed, step-by-step techniques and protocols for constructing, evaluating, and using enzyme- and microbial-based biosensors. Ideal for novices starting research in their field or experienced researchers wanting to use a biosensor for a specific analytical measurement, the methods detailed here allow biochemists, analytical chemists, microbiologists, and engineers to successfully apply biosensor technology to their specific problems. The techniques include classical enzyme biosensors based on potentiometric, amperometric, conductimetric, optical, and thermal transducers, as well cell-based biosensors based on amperometric and optical transducers. A companion volume, Affinity Biosensors: Protocols and Techniques, by Rogers & Mulchandani, concentrates on cell- and affinity-based biosensors.

The many thousands of human-made and other chemical compounds present in the environment offer a serious challenge to our btosphere. It is appropriate, therefore, that our response to these products of human kno- edge and ingenuity should draw on a body of mtenstve scientific endeavor that is no less impressive. Bioremediation offers the possibility of harnessing the diversity of the biosphere to degrade, remove, alter, or otherwise detoxify these various chemicals. It brings together scientists from a wide variety of disciplines and backgrounds, such as microbiology, molecular biology, a- lytical chemistry, and chemical and environmental engineering, among o- ers. These different fields, each with its own individual approach, have actively contributed to the development of bioremediation research tn recent years. The prmcipal objective of Bioremediation Protocols is to make the fruits of some of this research available in a different format to that of the textbook or journal article. It provides a selection of clearly written laboratory pro- cols presented as stepwise, easy-to-follow mstructions. In common with p- wous volumes in this and the companion Methods in Molecular Biology series, an extensive “Notes” section is provided with each chapter. This contains u- ful mformation (of a type often not normally included m a research paper) supplementmg the protocol. Reviews and case studies are also included to provide a deeper context to the methods chapters.

It was our intention and goal to bring together m Biopestzcides Use and Delavery the latest advances in the science and technology of the evolving field of biopesticides In the context of crop protectton, btopesttcides are a key component of integrated pest management (IPM) programs, m which biopesticides are delivered to crops m inundative quantities, vs the mocu- tive approach, which is charactertstic of classical biological control. Although there are several definitions of biopesttcides m the literature, we chose to define them as either microbials themselves or products derived from microbials, plants, and other biological entities. In the developed, industrial countries, primarily in Western Europe and the United States, biopesticides are receiving more practical attention, smce they are viewed as a means to reduce the load of synthetic chemical pes- tides m an effort to provide for safer foods and a cleaner envtronment.In the developing countries, biopestictdes are viewed as having the potential to - ploit nattve resources to produce crop protection agents that would replace imported chemical pesticides and conserve much-needed hard currencies These trends are well represented by the dynamic growth of engineered crops expressing the delta-endotoxm insecticidal protem crystals of Bacillus thuringzenszs (B. t ) m corn, cotton, and potatoes and the development of - combinant B. t.

A cutting-edge collection of detailed, step-by-step techniques and protocols for constructing, evaluating, and using affinity-based biosensors. Ideal for novices starting research in their field or experienced researchers wanting to use a biosensor for a specific analytical measurement, the methods detailed here allow biochemists, analytical chemists, microbiologists, and engineers to successfully apply biosensor technology to their specific problems. The techniques include the use of antibodies and membrane receptors to construct optical, thermal, acoustic, and electrochemically based biosensors. Additional techniques involve antibodies, receptors, nucleic acids, liposomes, and eukaryotic cells. A companion volume, Enzyme and Microbial Biosensors: Protocols and Techniques, by Mulchandani & Rogers, concentrates on enzyme-biosensors.

Rajni Hatti-Kaul and her expert coauthors combine theory, methodology, and applications in a practical collection of easily reproducible protocols for bioseparations in aqueous two-phase systems (ATPS). The protocols range from established methods to cutting-edge techniques with potential biotechnological applications. Among the methods detailed are those for ATPS preparation and characterization, for partitioning applied to soluble molecules and particulates (including whole cells, membranes, and organelles), and for the isolation and purification of proteins - including a glimpse of large-scale handling of two-phase separations. Practical and informative, with its detailed guidelines allowing researchers to adapt specific systems to their own separation needs, Aqueous Two-Phase Systems: Methods and Protocols demonstrates the scope and utility of two-phase aqueous systems in both basic and applied research.

We are in a phase of the evolution of biotechnology in which the true and potential commercial importance of carbohydrates is becoming appre- ated more fully. Progress in providing hard facts to establish the commercial value ofpolysaccharides and oligosaccharides is limited, as always, by lack of funding and by a relative shortage of skilled practitioners in the production and analysis of those materials. Carbohydrate science has a reputation, not unmerited, for technical difficulty owing to the structural similarity of the many monosaccharide monomers and the potential, and real, complexity of oligosaccharides and polysaccharides, particularly heterosaccharides conta- ing many different monomers. Modem analytical and synthetic methods, in many cases using enzyme technology, are beginning to allow this complexity to be unraveled. Carbohydrate Biotechnology Protocols is aimed at those newcomers who have an interest in the production and use of carbohydrate materials, but have shied away from involvement for lack of detailed descriptions of appropriate methods, including the type of practical hints that may be provided by those skilled in those methods, but that are rarely described in research papers. The majority of the contributions to this book conform to the established format of the Methods in Biotechnology series. They begin with the theoretical and c- mercial background to the method or group of methods, provide a list of the reagents and equipment required for the procedure, then give a detailed st- by-step description of how to carry out the protocol.

Mohamed A. Desai and a team of experienced biotechnologists review both conventional and novel isolation techniques used in industrial applications for the downstream processing of protein molecules. These techniques include primary and secondary separations during the isolation of biomolecules, as well as unique laboratory-scale research methods from academia with a potential for scale-up. Also treated are various strands of the downstream biological process essential for a successful product license application, including both the validation of DSP stages, and the design and validation of viral clearance stages during the purification process. Downstream Processing of Proteins: Methods and Protocols provides scientists everywhere, but particularly in the biopharmaceutical and biotechnology industry, with a much-needed introduction to this critical technology.

In addition, it provides a step-by-step description of the most recent developments in applied biotechnological processes useful for screening, evolution, production, immobilization, and use of enzymes.

Enzymes and whole cells are able to catalyze the most complex chemical processes under the most benign experimental and environmental conditions. In this way, enzymes and cells could be excellent catalysts for a much more sustainable chemical industry. However, enzymes and cells also have some limitations for nonbiological applications: fine chemistry, food chemistry, analysis, therapeutics, and so on. Enzymes and cells may be unstable, difficult to handle under nonconventional conditions, poorly selective toward synthetic substrates, and so forth. From this point of view, the transformation—from the laboratory to industry—of chemical processes catalyzed by enzymes and cells may be one of the most complex and exciting goals in biotechnology. For many industrial applications, enzymes and cells have to be immobilized, via very simple and cost-effective protocols, in order to be re-used over very long periods of time. From this point of view, immobilization, simplicity, and stabilization have to be strongly related concepts. Over the last 30 years, a number of protocols for the immobilization of cells and enzymes have been reported in scientific literature. However, only very few protocols are simple and useful enough to greatly improve the functional properties of enzymes and cells, activity, stability, selectivity, and related properties.
