Trypsin-Chymotrypsin mixture is the co-crystal of chymotrypsin and trypsin, so it has the properties of both.
The activity of both hydrolysing casein is as much as chymotrypsin. But the activity of its chymotrypsin to hydrolyse N-benzoyl-L-tyrosine ethyl ester (Btee) is three times higher than chymotrypsin. The activity of hydrolysing ester bond is similar to that of trypsin.
It is stable when dry and easy to be inactivated in solutions.
In clinical field it’s used for anti-inflammatory drugs.
