English Name: α - chymotrypsin (bovine); chymotrypsin (bovine); TLCK chymotrypsin
Other names: α - chymotrypsin; α - chymotrypsin; chymotrypsin; chymotrypsin
CAS No.: 9004-07-3
Level: USP
Molecular weight: 25kDa
Activity: ≥ 1500usp units / mg
Activity definition: at 25 ºC, pH 7.0, the amount of enzyme reducing 0.001 of optical density value at 237nm per minute is 1 atee unit (U)
Loss on drying: ≤ 5.0%
Burning residue: ≤ 2.5%
Shape: white or nearly white crystalline or amorphous powder. Odorless. Soluble in water and dilute buffer solution. The optimum pH is 7.5-8.5. Isoelectric point (PI) 8.3. The median lethal dose (rat, vein) was 84 mg / kg. It can preferentially hydrolyze the peptide bond formed by the carboxyl group of L-tyrosine and L-phenylalanine. Chymotrypsin activity can be inhibited by heavy metals and natural trypsin inhibitors.
Purpose: biochemical research. Protein decomposition and digestion. Proteolytic enzyme, which is used for protein hydrolysis without the existence of exogenous trypsin activity. The carboxyl end of the hydrolyzed peptide bond has aromatic or long hydrophobic chain (Tyr, Trp, Phe, met) peptide bond.
Storage: - 20 ºC
