Detection of Human Carbonic Anhydrase XII/CA12 by Western Blot.
Western blot shows lysates of human kidney tissue and A549 human lung carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Carbonic Anhydrase XII/CA12 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2190) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Carbonic Anhydrase XII/CA12 at approximately 45-50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human Carbonic Anhydrase XII/CA12 by Simple WesternTM.
Simple Western lane view shows lysates of A549 human lung carcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Carbonic Anhydrase XII/CA12 at approximately 60 kDa (as indicated) using 10 µg/mL of Goat Anti-Human Carbonic Anhydrase XII/CA12 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2190) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.
Detection of Carbonic Anhydrase XII/CA12 by Western Blot
Differential expression of CAIX and CAXII in patient-derived tumor grafts. Panel A. Frozen tissue samples from PDX tumors were homogenized in RIPA buffer containing protease inhibitor. Western blots were probed with antibodies for CAIX, CAXII, CAII, ER, E-cadherin, actin, and GAPDH. Panel B. Tumor growth rates of orthotopically implanted, cryo-preserved tumor tissue was evaluated in NOD/SCID mice. Panel C. Immunohistochemistry was utilized to evaluate expression of CAIX, CAXII, ER, and Ki67 in TNBC (HCl-001) and ER/PR-positive (HCl-011) tumors from Panel B. Magnification: primary objective magnification, 10x.

Background: Carbonic Anhydrase XII/CA12
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. CA12 is a type I membrane enzyme highly expressed in colon, kidney, prostate, intestine and activated lymphocytes and moderately expressed in pancreas, ovary, and testis (2, 3). It is over-expressed in some renal cell cancers and in glaucoma (2, 4). Two alternatively spliced forms exist, which either contains or lacks a 11 amino acid segment just before the transmembrane domain (5). The secreted, purified recombinant human CA12 contains the residues that are common for both forms.
