General description

Trypsin is a kind of serine protease that specifically hydrolyze peptide bond formed of carboxyl of basic amino acids Arginine and Leucine. The enzyme can easily be autolyzed. It is soluble in Water, insoluble in trichloromethane, ethanol, aether and glycerol. The optimum pH is 8.0. Calcium can delay the autolysis of Trypsin and promote the activity of pre-Trypsin.

The high purity trypsin of Beijing Geyuantianrun Bio-tech Co., Ltd. is purified by re-crystallization, and then by Ion Exchange Chromatography and ultra-filtration.
