General description

Chymotryupsin is white and light yellow crystal or amorphous powder, and easily soluble in the water, but insoluble in organic solvent. Relative molecular mass is 24000, and the optimum PH is 8~9. It is stable at a dry state, but will be quickly deactivated in water solution, most stable in the water solution with PH3~4. When it acts on the protein, it will hydrolyze the peptide bond formed by the carboxyl of L-tyrosine and L-phenylalanine in priority.

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.

Application

Ø  In the clinical, it always used to general trauma, wound healing that after surgery, anti-inflammatory, prevent local edema, hematocele, sprain hematoma, partial swelling that after breast surgery, tympanitis, rhinitis and so on. Use for the removal of cataract, Loose the lashes muscle ligament, reduce the cyst rupture and the hurt of retina.Besides, the combination use with the Trypsin and used as a broad-spectrum anti-inflammatory drugs.

Ø  as the auxiliary medicine of antibiotic and antifungal drugs,it is widely used in  the field of animal medicine and animal health industry.
