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). 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). The immunogen corresponds to the extracellular portion of human CA9.

Scientific Data Images for Human Carbonic Anhydrase IX/CA9 Antibody
Carbonic Anhydrase IX/CA9 in Human Colon.
Carbonic Anhydrase IX/CA9 was detected in immersion fixed paraffin-embedded sections of human colon using Mouse Anti-Human Carbonic Anhydrase IX/CA9 Monoclonal Antibody (Catalog # MAB21881) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm.
