    CA III Antibody (E-4) is a mouse monoclonal IgG2b antibody that detects carbonic anhydrase III (CA III) in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). CA III is a 260 amino acid cytoplasmic protein predominantly expressed in muscle tissue, where CA III plays a crucial role in regulating pH and facilitating the transport of carbon dioxide and bicarbonate across cell membranes. CA III is part of the alpha-carbonic anhydrase family and is activated by proton donors like imidazole, which enhances enzymatic activity, while being inhibited by compounds such as coumarins and sulfonamide derivatives, including acetazolamide. CA III′s ability to maintain acid-base balance is vital for muscle function, particularly during exercise, as CA III helps to prevent acidosis that can impair muscle performance. With specific expression in muscle and regulatory functions, CA III is an important target for studies related to muscle physiology and pathophysiology, making anti-CA III antibody (E-4) an essential tool for researchers investigating these processes.

    What blocking solution should I use with CA III (E-4): sc-271345 monoclonal antibody for Western blot?

    Asked by: TinTin
    Thank you for your question. We recommend blocking with Blotto (either TBS Blotto A: sc-2333 or TBS Blotto B: sc-2335). Our Western blot protocol can be found here: https://www.scbt.com/scbt/resources/protocols/western-immuno-blotting
