The main objective of this study was to develop an effective in-gel trypsin digestion protocol using aqueous-acetonitrile solvent system to facilitate MS analysis and maximize the number of identified proteins from biological samples. The procedure, where 80% acetonitrile was present in the trypsin reaction mixture, increased the number of matched peptides, and allowed the identification of more proteins with higher coverage than the common digestion protocol. Vimentin, annexins, tubulin, actin, peptidyl-prolyl cis-trans isomerase or alpha-enolase are examples of important proteins that change during the progress cancer. These were isolated from human breast cancer cells and were used for this study.
