During the course of evolution, an imbalance was created between the rate of vertebrate genetic adaptation and that of the lower forms of living organisms, such as bacteria and viruses. This imbalance has given the latter the advantage of generating, relatively quickly, molecules with unexpected structures and features that carry a threat to vertebrates. To compensate for their weakness, vertebrates have accelerated their own evolutionary processes, not at the level of whole organism, but in specialized cells containing the genes that code for antibody molecules or for T-cell receptors. That is, when an immediate requirement for molecules capable of specific interactions arose, nature has preferred to speed up the mode of Darwinian evolution in pref- ence to any other approach (such as the use of X-ray diffraction studies and computergraphic analysis). Recently, Darwinian rules have been adapted for test tube research, and the concept of selecting molecules having particular characteristics from r- dom pools has been realized in the form of various chemical and biological combinatorial libraries. While working with these libraries, we noticed the interesting fact that when combinatorial libraries of oligopeptides were allowed to interact with different selector proteins, only the actual binding sites of these proteins showed binding properties, whereas the rest of the p- tein surface seemed "inert. " This seemingly common feature of protein- having no extra potential binding sites--was probably selected during evolution in order to minimize nonspecific interactions with the surrounding milieu.

Shmuel Cabilly presents in Combinatorial Peptide Library Protocols a collection of new and unique techniques for the construction and use of peptide libraries. These powerful methods-often detailed here by their pioneers-include protocols for the chemical synthesis of peptide libraries, for constructing peptide libraries that are displayed on the surface of filamentous phage or bacteria, and for the rapid screening of these libraries for molecules with biospecific properties. Additional methods permit identifying specific enzyme substrates, investigating the recognition spectra of various binding proteins, epitope mapping, and identifying mimotopes. Combinatorial Peptide Library Protocols offers novice and experienced investigators alike the ability to select molecules from a randomized pool having specific biological activities. Its state-of-the-art techniques, combined with clear step-by-step instructions, make this book an essential tool in the selection of peptides suitable for drug development.
