ELISA 抗体对套装(非即用型)组分
1. Capture Antibody 0.2 mg/mL of mouse anti-CPB1 monoclonal antibody, Dilute to a working concentration of 2 μg/mL in CBS before coating. (Catalog: # 10501-MM06) 2. Detection Antibody 0.5 mg/mL of rabbit anti-CPB1 monoclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 0.25 μg/mL in detection antibody dilution buffer before use. (Catalog: # 10501-R108) 3. Standard Each vial contains 30 ng of recombinant CPB1. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 400 pg/mL is recommended.

Carboxypeptidase B1, also well known as pancreatic procarboxypeptidase B (PCPB), is a highly pancreas -specific protein (PASP), and has been identified previously as a serum marker for acute pancreatitis and pancreatic graft rejection. As the prototype for those human exopeptidases that cleave off basic C-terminal residues, CPB1 specifically cleaves the C-terminal Arg and Lys residues with a preference for Arg. The B1 and B2 forms of procarboxypeptidase B differ from each other mainly in isoelectric point.The deduced amino acid sequence of PCPB predicts a 416-amino acid preproenzyme consisting of a 15-aa signal peptide, a 95-aa activation peptide and a 37-aa mature chain. The secreted PCPB zymogen is converted to enzymatically active CPB1 by limited proteolysis by trypsin.
