The use of synthetic peptide immunogens as a means to generate specific immunological reagents for a variety of purposes has increased markedly in recent years. In this chapter, we outline some of the salient factors to be considered when designing peptide immunogens and describe basic methodologies for the conjugation of short synthetic peptides to immunogenic carrier proteins.

The decreasing number of approved drugs produced by the pharmaceutical industry, which has been accompanied by increasing expenses for R&D, demands alternative approaches to increase pharmaceutical R&D productivity. This situation has contributed to a revival of interest in peptides as potential drug candidates. New synthetic strategies for limiting metabolism and alternative routes of administ...
