Trypsin, TPCK treated, 8-Pack
SKU #: 4370285
For research use only. Not for use in diagnostic procedures.
A modified (TPCK treated) serine protease that specifically hydrolyzes peptide bonds at the carboxyl side of lysine and arginine residues. Modified trypsin is treated with N-tosyl-L-phenylalanine chloromethyl ketone (TPCK) to inactivate extraneous chymotryptic activity. Each package contains 8 vials containing 25 ?æg in each vial. We recommend 10ug of Trypsin per 100ug of protein. For serum/plasma experiments we recommend labeling 50 ug of protein per sample (therefore you will need only half as much trypsin). Note: Does not contain calcium chloride.
