General description
Trypsin-Chymotrypsin is the co-crystal of Chymotrypsin and Trypsin so it has the properties of both. The activity of hydrolyzingcasein is as much as that of Chymotrypsin. But the activity ofits Chemotrypsin to hydrolyze N-Benzoyl-L-tyrosineethyl ester(BTEE)is three times higher than thatof Chemotrypsin. Theactivity of hydrolyze ester bond similar to that of Trypsin.It is stable when dry and easy to be inactivated in solutions. The optimum pHis 7.0-8.0.
The high purity Trypsin-Chymotrypsin of Beijing Geyuantianrun Bio-tech Co., Ltd.. is purified byre-crystallization, and then by ultra-filtration.
