General description

Trypsin-Chymotrypsin is the co-crystal of Chymotrypsin and Trypsin so it has the properties of both. The activity of hydrolyzing casein is as much as Chymotrypsin. But the activity of its Chemotrypsin to hydrolyze N-Benzoyl-L-tyrosine ethyl ester(BTEE)is three times higher than Chemotrypsin.The activity of hydrolyze ester bond similar to that of Trypsin. It is stable when dry and easy to be inactivated in solutions. The optimum pH is 7.0-8.0.

The high purity Trypsin-Chymotrypsin of Beijing Geyuantianrun Bio-tech Co., Ltd.. is purified by re-crystallization, and then by ultra-filtration.
