Detection of Human Carbonic Anhydrase IX/CA9 by Western Blot. Western blot shows lysates of U-87 MG human glioblastoma/ astrocytoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Carbonic Anhydrase IX/CA9 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2188) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (HAF109). A specific band was detected for Carbonic Anhydrase IX/CA9 at approximately 58 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Carbonic Anhydrase IX/CA9 in A431 Human Cell Line. Carbonic Anhydrase IX/CA9 was detected in immersion fixed A431 human epithelial carcinoma cell line using Goat Anti-Human Carbonic Anhydrase IX/CA9 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2188) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Carbonic Anhydrase IX/CA9 in Human Colon Cancer Tissue. Carbonic Anhydrase IX/CA9 was detected in immersion fixed paraffin-embedded sections of human colon cancer tissue using Goat Anti-Human Carbonic Anhydrase IX/CA9 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2188) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; CTS008) and counterstained with hematoxylin (blue). Specific labeling was localized to the plasma membrane of epithelial cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: Carbonic Anhydrase IX/CA9
Carbonic Anhydrase (CA) catalyzes the reversible reaction of CO2 + H2O = HCO3- + H+, which is fundamental to many processes such as respiration, renal tubular acidification and bone resorption (1-3). Topics in the CA meeting (6th International Conference on the CAs, June 20-25, 2003, in Slovakia) ranged from use of CAs as markers for tumor and hypoxia in clinic, as nutritional supplement in milk, and as a tool for CO2 removal and mosquito control in industry. CA9, also known as membrane antigen MN and renal cell carcinoma (RCC)-associated antigen G250, is a transmembrane enzyme expressed primarily in carcinoma cells. It is one of the best markers for hypoxia and for RCC (4, 5). Recombinant human CA9 corresponds to the extracellular portion of human CA9.
