Химотрипсин протеиназы

Chymotrypsin is a kind of protease that can preferentially hydrolyze the peptide bond formed of the carboxyl of L-Tyrosine and L-Phenylalanine. The optimum pH is 8.0-9.0 for the hydrolysis. The activity of Chymotrypsin can be blocked by heavy metal and other natural trypsin inhibitors to different levels. Clinically, Chymotrypsin can be used for wound healing, inflammation resistance, preventing from local edema, gore, wrick haematoma, and edema after breast surgery, tympanitis and rhinitis etc. High purity Chymotrypsin produced by Beijing Geyuantianrun Bio-tech Co., Ltd. is separated from bovine pancreas, and then purified by Ion Exchange Chromatography to get rid of other kinds of remaining proteins.Quality standard ItemSpecificationmethodPropertiesWhite or almost white freeze-dry powderIdentificationQualifiedUSP32Checking-uppH3.0-5.0EP6.0Turbidity of solutionclearUSP32Trypsin≤1USP32Loss in drying≤5.0%USP32Ignition residue≤2.5%USP32Effect≥1000USP units/mgUSP32 ConclusionThe product is qualified by the standard ofAmerican Pharmacopoeia, also by the standards of European Pharmacopoeia andChina Pharmacopoeia.
