A valuable collection of new and unique techniques for the construction and use of peptide libraries. These powerful methods 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. 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.
