This volume serves to aid researchers working in the recombinant protein production field by describing a wide number of protocols and examples. Chapters describe recombinant protein production in different expression systems, prokaryotic and eukaryotic expression systems, purification protocols, characterization of insoluble proteins and a general overview of interesting applications of insoluble proteins. Written in the format of the highly successful Methods in Molecular Biology series, each chapter includes an introduction to the topic, lists necessary materials and reagents, includes tips on troubleshooting and known pitfalls, and step-by-step, readily reproducible protocols. Authoritative and cutting-edge, Insoluble Proteins: Methods and Protocols, Second Edition aims to be a useful practical guide to researches to help further their study in this field.
