IgA purified from normal human colostrum
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide as preservative
Anti-Human IgA (α-chain specific) antibody is suitable for use in quantitative precipitin assay (2.5-5 mg/mL), immunoelectrophoresis and Ouchterlony double diffusion (1:16).
IgA is a secretory glycoprotein antibody that regulates the physiological balance between commensal intestinal bacteria and the defenses of the host immune system. It is the highest generated antibody isotype. IgAs are mainly secreted in the intestinal mucosa and prevent the commensal microorganisms from invading the intestines [2][1][3]
Anti-Human IgA (α-chain specific) antibody is specific for the α-chain of IgA in humans. The product reacts with human IgA when tested against purified human IgA, IgG, IgM, and Bence Jones κ and lambda myeloma proteins.
