Methods of Protein Separation - - Bog - Springer-Verlag New York Inc. - Plusbog.dk

This open-end treatise on methods concerning protein separation had its beginning in an American Chemical Society symposium entitled "Con­ temporary Protein Separation Methods" which was held in Atlantic City, New Jersey in September 1974. The purpose of the symposium-and subse­ quently of the present work-was to review the available modern techniques and underlying principles for achieving one of the very important tasks of experimental biology, namely the separation and characterization of proteins present in complex biological mixtures. Physicochemical characterization was covered only as related to the parent method of fractionation and there­ fore involved mostly mass transport processes. Additionally, the presentation of methods for gaini. ng insight into complex interacting protein profiles was considered of paramount importance in the interpretation of separation patterns. Finally, specific categories of proteins (e. g. , chemically modified, deriving from a specific tissue, conjugated to different moieties, etc. ) require meticulous trial and selection andjor modification of existing methodology to carry out the desired separation. In such cases, the gained experience provides valuable guidelines for further experimentation. Although powerful techniques exist today for the separation and related physicochemical characterization of proteins, many biological fractionation problems require further innovations. It is hoped that the description in the present treatise of some of the available separation tools and their limitations will provide the necessary integrated background for new developments in this area.

Atlas of Protein Spectra in the Ultraviolet and Visible Regions - Donald M. Kirschenbaum - Bog - Springer-Verlag New York Inc. - Plusbog.dk

Once you have seen the spectrum of one protein you have seen the spectra of all pro­ teins. Or so it would seem. While the general characteristics of the absorption curve may appear to be similar for all proteins (i. e. , in acid and neutral solution there is a minimum at 250 nm, a maximum at 278-282 nm, and no absorption above 310 nm; in alkaline solution the maximum and minimum shift to longer wavelengths), there are subtle differences which can be seen when the spectra of many proteins are compared. It is these differences which reflect changes in amino acid content and in the milieu in which the protein has been dissolved. The spectra in this book provide samples of these subtle spectral differences and permit comparisons to be made. This book was prepared to have its index read and its contents referred to. For the reader who desires to know what a protein spectrum looks like in acid and alkaline media, after X-ray or UV irradiation, or after photo-oxidation or B-bromosuccinimide treatment, spectral representations of all these experimental situations and many others are available. The indicies were prepared to provide the maximum information with the minimum effort. In addition to an alphabetical listing, all spectra are referred to by species, tissues, and the organs from which they were taken. There are also "environmental" indicies related to the treatment the proteins received prior to having their spectra taken. Technical information concerning instrumentation is lacking.

Food Allergens - Marija Gavrovic Jankulovic - Bog - Springer-Verlag New York Inc. - Plusbog.dk

A food allergen has the ability to first elicit an IgE response, and then, on subsequent exposures, a clinical response to the same or similar protein. How harmless food protein becomes recognized by the mucosal immune system as an allergen remains an open question and more data are needed to explain how regulatory mechanisms of the mucosal immune system fail and result in allergic sensitization to dietary antigens. Some biochemical characteristics associated with food allergens, such as the presence of multiple, linear IgE-binding epitopes and the resistance of the protein to digestion and processing, seem to predominate among food allergens. Digestion susceptibility of food allergens that sensitize via the gastrointestinal tract and stability to food processing conditions are inherently related to protein structural features. Thereby, physiological changes in the digestion process, pathological conditions affecting digestion, as well as procedures and food processing conditions that affect protein structure may all have a profound effect on the sensitizing potential and allergenicity of food proteins. In addition, signals coming from the diet and micro biome can modulate regulatory mechanisms of the mucosal immune system and influence mucosal immunity and intestinal barrier function. The detection of allergenic ingredients in food products has received increased attention from the food industry and legislative and regulatory agencies over recent years. This has resulted in the improvement of applied safety measures that provide protection for food-allergic consumers and development of sensitive and highly specific analytical methods of food allergens detection. Food allergy is an important and common health issue and therefore there is a need to characterize the sensitizing potential of newly introduced proteins in genetically engineered foods. A combination of in vitro and in silico methods provide information that contributes to safety assessment. Suitable in vivo models may provide a more holistic assessment of allergenic potential of novel food proteins.

MHC Molecules: Expression, Assembly and Function - Robert G. Urban - Bog - Springer-Verlag New York Inc. - Plusbog.dk

3 nant expression systems have been used to make MHC molecules con­ taining a single peptide of interest. To date, fifteen single peptide class I structures (incorporating three different HLA and two different H-2 allotypes/isotypes) and four additional class II structures (two single peptide complexes and two superantigen complexes) have been reported. These advances have enabled us to study the atomic detail of antigen presentation and the general mechanisms behind peptide binding, and begin to construct models of T cell recognition. Another area of research which has exploded over the past five years has been the identification of MHC-associated peptides. There are several methods one can use to determine the sequence identity of MHC restricted peptides. Historically, the most successful technique, albeit crude and encumbered with serious limitations, has been the use of overlapping synthetic peptides and T cell clones. Unfortunately, this method absolutely requires: (i) knowledge of the target antigen; (ii) availability of T cell clones; and (iii) a relatively short overall length for the target source protein, such that a set of overlapping pep tides can be affordably synthesized. Briefly, the entire sequence of the tar­ get protein is chemically synthesized using overlapping peptides which are then screened for biological activity using standard T cell presen­ tation assays. Despite its limitations, this method was used to identify the first immunodominant epitopes reported in the literature and con­ tinues to be used successfully today.
