Rabbit Monoclonal Antibody to Human Carboxypeptidase M
Carboxypeptidase M, also known as CPM, is a membrane-bound arginine /lysine carboxypeptidase which is a member of the carboxypeptidases family. These enzymes remove C-terminal amino acids from peptides and proteins and exert roles in the physiological processes of blood coagulation/fibrinolysis, inflammation, food digestion and pro-hormone and neuropeptide processing. Among the carboxypeptidases CPM is of particular importance because of its constitutive expression in an active form at the surface of specialized cells and tissues in the human body. CPM in the brain appears to be membrane-bound via a phosphatidylinositol glycan anchor. CPM is widely distributed in a variety of tissues and cells. The amino acid sequence of CPM indicated that the C-terminal hydrophobic region might be a signal for membrane attachment via a glycosylphosphatidylinositol (GPI) anchor. CPM is involved in peptide metabolism on both the cell surface and in extracellular fluids. CPM functions not only as a protease but also as a binding partner in cell-surface protein-protein interactions.

Recombinant Human Carboxypeptidase M / CPM Protein
Western blot: This antibody can be used at 1-2 μg/mL with the appropriate secondary reagents to detect Human CPM in WB.Using a DAB detection system, the detection limit for Human CPM is approximately 0.5 ng/lane under non-reducing conditions and 0.25 ng/lane under reducing conditions.ELISA: This antibody can be used at 0.1-0.2 μg/mL with the appropriate secondary reagents to detect Human CPM. The detection limit for Human CPM is approximately 0.0049 ng/well.
This antibody was obtained from a rabbit immunized with purified, human cell-derived, recombinant Human Carboxypeptidase M / CPM
