Product information "Tosyl-L-phenylalaninchloromethylketon (TPCK)"

TPCK is an irreversible, specific inhibotor for chymotrypsin and inhibits the thrombin-like protease Cerastocytin. Trypsin is not inhibited by TPCK. The pH optimum for inhibition throµgh alkylation by TPCK of Chymotrypsin is pH7.2. Chymotrypsinogen is not inhibited by TPCK. The bacterial Serin-proteases Re, Fa and So from E.coli are completely inhibited by 0.5 to 1 mM TPCK. TPCK is used for the production of Chymotrypsin free Trypsin. TPCK solutions are stable at pH below 7.0 at RT, nevertheless it is recommended to store solutions at +2°C to +8°C. TPCK is not stable at pH above 7.0. Stock solutions of 3mg/mL to 20mg/mL are prepared in MeOH or EtOH. Working concentrations: 10µg/mL to 100µg/mL.
