Carboxypeptidase B

100% Animal Origin Free 

CAS No 9025-24-5 

Product Overview

Achieve unmatched accuracy in protein characterization and biopharmaceutical production with our Recombinant Carboxypeptidase B. Engineered for high specificity and zero animal-derived components, this enzyme is the industrial standard for removing C-terminal Arginine and Lysine residues with total confidence. 

Why is Recombinant Carboxypeptidase B the Industry Choice? 

Traditional Carboxypeptidase B is often sourced from porcine pancreas, which introduces the risk of viral contaminants and unwanted protease activity. Our recombinant version, expressed in Pichia pastoris, offers a cleaner, safer, and more stable alternative.
