Bacterial Amyloids

This detailed volume introduces different methods to assess the structure and folding of bacterial amyloids and analyze their functions, either in vitro or in vivo. Despite their initial association with neurodegenerative diseases, there is now increasing evidence of alternative roles for amyloids, with beneficial aspects for cells. In particular, prokaryotes use amyloids as functional assemblies, where they are key players in the cell's physiology. Written for the highly successful Methods in Molecular Biology series, 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.
Authoritative and up-to-date, Bacterial Amyloids: Methods and Protocols is an ideal guide for experts and novices alike to further explore these crucial protein assemblies.

Includes cutting-edge techniques Provides step-by-step detail essential for reproducible results Contains key implementation advice from the experts
