The Low Molecular Weight Proteome, 2013
Methods and Protocols
Methods in Molecular Biology Series, Vol. 1023

Small proteins with molecular weights of <25 kDa are involved in major biological processes such as ribosome formation, stress  adaption and cell cycle control. The study of the low-molecular-weight proteome has identified many central regulators of biology such as cytokines, chemokines, peptide hormones and proteolytic fragments of larger proteins.  Due to the unique features of these proteins, the technical challenges are different  from those in ?common? proteomics. In The Low Molecular Weight Proteome: Methods and Protocols expert researchers from the field provide protocols for analysis of low molecular weight proteins and peptides, protocols for such methods applied in clinical research and an up-to-date review of quantitative protein profiling by labeling.  These include methods suitable for both peptide and protein analysis with focus on methods and application that can be used for small protein analysis. 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 key tips on troubleshooting and avoiding known pitfalls.

Authoritative and practical, The Low Molecular Weight Proteome: Methods and Protocolsis a useful resource for experienced proteomics practitioners as well as an aid to newcomers who wish to become acquainted with the theory and practice of a wide array of methods in analyzing small proteins or peptides.
