Scientific Data

Western Blot Detection of Human Carbonic Anhydrase IV/CA4 antibody by Western Blot. View Larger

Detection of Human Carbonic Anhydrase IV/CA4 by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line and human lung tissue. PVDF Membrane was probed with 2 µg/mL of Mouse Anti-Human Carbonic Anhydrase IV/CA4 Monoclonal Antibody (Catalog # MAB21861) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Carbonic Anhydrase IV/CA4 at approximately 35 kDa (as indicated). This experiment was conducted under non-reducing conditions and using Immunoblot Buffer Group 1.

Background: Carbonic Anhydrase IV/CA4

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). Topics in a CA meeting (6th International Conference on the CAs, June 20‑25, 2003, Slovakia) ranged from the use of CAs as markers for tumor and hypoxia in the clinic, as a nutritional supplement in milk, and as a tool for CO2 removal and mosquito control in industry. CA4 is a GPI‑anchored membrane enzyme expressed on the luminal surfaces of pulmonary (and certain other) capillaries and of proximal renal tubules. It functions as the principal CO2 taste sensor (2). In addition, a genetic mutation (Arg 14 to Trp in the signal peptide) of CA4 was found to co‑segregate with the RP17 form of retinitis pigmentosa in two large families and was not found in 36 unaffected family members or 100 controls (3).
