Peptide libraries are a highly useful tool for drug development. While most preparations of peptide libraries are laborious during either the synthesis or its screening, the SPOT synthesis offers the possibility of directly synthesizing large numbers of peptides on a planar surface. As a positionally addressable, multiple solid-phase synthesis technique, the synthesis allows a very convenient handling during the screening of that peptide library in a form of an array. This publication will provide protocols for the basic procedures of the SPOT synthesis and references to some important literature regarding that technique and its application.
