Product Name:Carboxypeptidase B
English Name:Carboxypeptidase B
CAS No.:9025-24-5
Aliases:Protaminase, Pancreatic carboxypeptidase B, Peptidyl-L-lysine hydrolase
Physical Properties:White or off-white lyophilized powder; soluble in water and dilute buffers; molecular weight approximately 34 kDa; isoelectric point about 6.0; optimum pH 7.0–8.0; belongs to a zinc metalloprotease, inhibited by EDTA or o-phenanthroline; stable over pH 4–11, but readily loses activity above 55 °C.
Uses:Carboxypeptidase B specifically hydrolyzes C-terminal arginine and lysine residues in peptides and proteins. It is widely used in protein and peptide sequence analysis, peptide mapping, and biopharmaceutical processes to remove C-terminal basic amino acid impurities. It is also used in studies involving the conversion of trypsinogen to trypsin.
Technical Specifications:
Appearance: White or off-white lyophilized powder
Purity: ≥98% by SDS-PAGE
Activity: One unit hydrolyzes 1 μmol of hippuryl-L-arginine per minute at pH 7.6 and 25 °C
Molecular weight: Approximately 34 kDa (SDS-PAGE)
Storage: Store at -20 °C, avoid repeated freeze-thaw cycles
