Protein Arginylation

This second edition provides updated and new chapters that detail comprehensive overview of all the existing methods on analyzing protein arginylation. Chapters guide readers through the early methods utilizing crude protein preparations and whole-cell assays to the latest advanced methods involving recombinant protein techniques, antibodies, high precision mass spectrometry, and chemical probes. 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 methods, includes tips on troubleshooting and known pitfalls, and step-by-step, readily reproducible protocols.

Cutting-edge and thorough, Protein Arginylation: Methods and Protocols, Second Edition  aims to be of interest to novice researchers involved in posttranslational arginylation research and researchers working on a broad range of posttranslational modifications.
