Overview

Product Describtion:

Chymotrypsin preferentially catalyzes the hydrolysis of peptide bonds involving L-isomers of tyrosine, phenylalanine and tryptophan. It also readily acts upon amides and esters of susceptible amino acids. Chymotrypsin catalyzes the hydrolysis of bonds of leucyl, methionyl, asparaginyl and glutamyl residues.Three times crystallized alpha chymotrypsin which is an activation product of a 3X crystallized zymogen. Dialyzed against 1mM HCl and lyophilized.
