Anti-IgA Antibody

This unconjugated rabbit polyclonal reagent from Antibodies.com targets human IgA and is validated for Western Blot detection. Supplied as 500 µg in liquid format, the antibody belongs to the IgG isotype class and recognizes immunoglobulin A in human samples. The polyclonal composition enables binding across multiple epitopes of the IgA heavy chain, producing clear and reproducible bands in immunoblot assays. For best results, store refrigerated and protect from light; aliquot upon first use to limit freeze-thaw cycles and preserve binding activity across multiple experiments. Researchers studying mucosal immunity, B-lymphocyte function, and immunoglobulin isotype expression can apply this unconjugated primary antibody with their preferred HRP-conjugated or fluorescent secondary detection reagent.
