General description
Peptidyl-L-lysine (-L-arginine) hydrolase. Carboxypeptidase B is secreted as a zymogen (pro-carboxypeptidase B) from the pancreas.
Application
Carboxypeptidase B has been used for the mass spectroscopy analysis ofanti-K11/K48 bispecific antibody.
Biochem/physiol Actions
Carboxypeptidase B is a Zn2+-metalloprotease, which catalyzes the hydrolysis of the basic amino acids L-Lys and L-Arg from the C-terminal position in polypeptides.
Preparation Note
Inhibitors: Chelating agents and basic amino acids
Store at -15–-25 °C. (Freeze only once in aliquots!)
Analysis Note
Contaminants: <5mU chymotrypsin/mg protein, < 0.007mU trypsin/mg, <2% carboxypeptidase A. Potential chymotrypsin and trypsin activities are eliminated by DFP treatment.
Other Notes
For life science research only. Not for use in diagnostic procedures.
