General description
Chymotrypsin is a porcine (Bovine) pancreas extracted endopeptidase that can preferentially hydrolyze the peptide bond formed of the carboxyl of L-Tyrosine and L-Phenylalanine. The optimum pH is 8.0 for the hydrolysis. The activity of Chymotrypsin can be blocked by heavy metal and other natural trypsin inhibitors to different levels.
The high purity Chymotrypsin of Beijing Geyuantianrun Bio-tech Co., Ltd. is purified by re-crystallization, and then by Ion Exchange Chromatography and ultra-filtration.
