Length [aa]307
Molecular Weight35.1 kDa
Endotoxin Levels< 0.1 ng/µg of protein (<1EU/µg)
Biological ActivityCarboxypeptidase-B sequentially cleaves C terminal K and R residues.
Species ReactivityRat
Buffer20mM Tris, pH 8.0 + 50mM NaCl
ReconstitutionCentrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer (e.g. PBS) containing a carrier protein (e.g. 0.1% BSA) and store in working aliquots at -20°C to -80°C.
Stability and StorageThe lyophilized protein is stable at room temperature for 1 month and at 4°C for 6 months. Reconstituted working aliquots are stable for 1 week at 2°C to 8°C and for 3 months at -20°C to -80°C.
SynonymsCpb1; Cpb
DescriptionProteases (also called Proteolytic Enzymes, Peptidases, or Proteinases) are enzymes that hydrolyze the amide bonds within proteins or peptides. Most proteases act in a specific manner, hydrolyzing bonds at or adjacent to specific residues or a specific sequence of residues contained within the substrate protein or peptide. Proteases play an important role in most diseases and biological processes including prenatal and postnatal development, reproduction, signal transduction, the immune response, various autoimmune and degenerative diseases, and cancer. They are also an important research tool, frequently used in the analysis and production of proteins. Carboxypeptidase-B sequentially cleaves C terminal K and R residues. Recombinant rat Carboxypeptidase-B is a 35.1 kDa protein consisting of 307 amino acids.
