Western Blot Detection of Human Carboxypeptidase M antibody by Western Blot. View Larger

Detection of Human Carboxypeptidase M by Western Blot. Western blot shows lysates of human placenta tissue and human kidney tissue. PVDF membrane was probed with 0.5 µg/mL of Mouse Anti-Human Carboxypeptidase M Monoclonal Antibody (Catalog # MAB7457) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Carboxypeptidase M at approximately 58-65 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Carboxypeptidase M in Human Placenta. Carboxypeptidase M was detected in immersion fixed paraffin-embedded sections of human placenta using Mouse Anti-Human Carboxypeptidase M Monoclonal Antibody (Catalog # MAB7457) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counter-stained with hematoxylin (blue). Specific staining was localized to plasma membranes of decidual cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: Carboxypeptidase M

Carboxypeptidase M (CPM) is a 50‑65 kDa monomer that belongs to the regulatory CPN/E subfamily, peptidase M14 family of enzymes. It is widely expressed, being found on macrophages, fibroblasts, endothelial cells, oligodendrocytes and Schwann cells, dendritic cells, osteoblasts and bronchial epithelium. Carboxypeptidase M is a GPI‑linked glycoprotein that is best known as a peptidase that cleaves basic amino acids (aa) from the carboxyterminal of a number of peptides, including EGF and bradykinin. It is also known to bind to apparent substrates and undergo a conformational change that links it with the kinin B1 GPCR, initiating signal transduction. Mature human Carboxypeptidase M is 406 aa in length (aa 18-423). It contains one large enzymatic region (aa 19-310) and two critical glutamic acid residues at Glu260 and Glu264. Like many GPI‑linked proteins, Carboxypeptidase M undergoes solubilization and is reportedly found in urine and amniotic fluid. Over aa 18-423 (mature Carboxypeptidase M), human Carboxypeptidase M shares 86% aa sequence identity with mouse Carboxypeptidase M.
