The Roles of Trypsin in Protein Analysis

What is Trypsin?

A proteome is a sum total of all the cellular proteins, this would include housekeeping proteins and proteins that are produced in response to a stimulus. Some proteins are produced only in a given cell type or tissue, others are produced in all cells, some proteins are only produced under certain given conditions adding to the complexity and heterogeneity of proteins in a proteome. Similarly, alternative splicing and post translational modifications all together combined can make the proteome very complex.
