A chemically modified trypsin that is resistant to autolysis and degradation. Trypsin specifically hydrolyzes amides, peptides, and proteins at the C-terminus side of arginine and lysine residues. This mass spectrometry grade trypsin is methylated, TPCK treated, and affinity purified. It is specifically designed for digestion of proteins for sequencing and peptide fragment analysis by mass spectrometry. A trypsin to protein ratio of 1:100 to 1:20 is recommended for mass spectrometry protocols. Note: 1 SET = 5 X 20 µg of modified trypsin and 1 ml of resuspension buffer.
