Buy Purified Native Human Cathepsin H (CatH), Human Liver.
Bulk Qty Available.

A more basic protein than Cathepsin B or L. Functions as both an aminopeptidase and endopeptidase. Cathepsin H, like cathepsin L and B, is involved in the catabolism of proteins in the lysosomal system.

Activity: greater than 1 unit per mg protein. One unit is defined as the amount of enzyme that hydrolyzes one umole of L-arginine-beta-napthylamide per minute at 40oC using 75 mM potasium phosphate, pH 6.8, with 1 mM EDTA and 3 mM cysteine as the activation buffer.

Prepared from tissue shown to be non reactive for HbsAG, anti-HCV, anti-HBc, and negative for anti-HIV 1 & 2 by FDA approved tests.
