The Eukaryotic RNA Exosome, 1st ed. 2020
Methods and Protocols
Methods in Molecular Biology Series, Vol. 2062

This volume provides a cross-section of RNA exosome research protocols, applied to a diversity of model organisms. Chapters guide readers through methods that e.g. delineate eukaryotic exosomes? origins in prokaryotes, probe its RNA substrates, adapter complexes and macromolecular interaction of networks, and establish critical structural-function relationships. 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.

 Authoritative and cutting-edge, The Eukaryotic RNA Exosome: Methods and Protocols aims to ensure successful results in the further study of this vital field.
