Proteomics – the analysis of the whole set of proteins and their functions in a cell – is based on the revolutionary developments which have been achieved in protein analysis during the last years. The number of finished genome projects is growing and in parallel there is a dramatically increasing need to identify the products of revealed genes. Acting on a micro level modern protein chemistry increases our understanding of biological events by elucidating the relevant structure-function relationships. The second edition of the successful title Microcharacterization of Proteins presents a current overview of modern protein analysis: From sample preparation to sequence analysis, mass spectrometry and bioinformatics it informs about the tools needed in protein research. This makes the book indispensable for everyone involved in proteomics!
