This volume provides basic and advanced laboratory protocols for the non-specialist and the experienced researcher. Chapters are divided into three parts covering synthesis and characterization of AMPs, studying the interaction of AMPs with model systems or bacteria, and assaying selected biological activities of AMPs. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
