Product Overview
This rabbit polyclonal antibody targets carbonic anhydrase 2 (gene CA2) in human, mouse and rat samples and is validated for flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 29.2 kDa, and the supplier reports an observed band at about 29 kDa.
Carbonic anhydrase 2 (CA2) is a fast, widely expressed cytosolic enzyme that converts CO2 and water into bicarbonate and protons. It is essential for acid secretion by osteoclasts during bone resorption and contributes to fluid secretion in the eye and kidney, making it a classic target in studies of pH regulation, osteopetrosis and glaucoma.

Samples with a confirmed band (WB): human 293T cells, human THP-1 cells, human HEL cells, rat kidney tissue, rat stomach tissue, mouse kidney tissue, mouse stomach tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human gastric cancer tissue, human liver cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in citrate buffer (pH 6).
Samples with a confirmed signal (flow cytometry): HT-29 cells, SW480 cells.
Immunogen
Recombinant human CA2 fragment (Ser2–Lys260), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 81.1% and 80.7%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places carbonic anhydrase 2 in the cytoplasm and cell membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
