ANTI-IMMUNOGLOBULIN A, HUMAN

Uses

Anti-Human IgA (α-chain specific) antibody is suitable for use in:

• enzyme-linked immunosorbent assay (ELISA)
• quantitative precipitin assay (2.5-5 mg/mL)
• immunoelectrophoresis
• Ouchterlony double diffusion (1:16)

Uses

Anti-Human IgA (α-chain specific) antibody is suitable for Ouchterlony double diffusion. The antibody was used for IgA quantification by ELISA in various studies. Antibody dilution of 1:4000 was used for passive hemagglutination inhibition assay.

General Description

Immunoglobulin A (IgA) is the primary antibody involved in mucosal immunity. It is identified by the presence of α-type heavy chains. IgA which is composed of two subclasses IgA1 and IgA2 can exist in a dimeric secretory form found in mucous secretions.

Biochem/physiol Actions

IgA is a secretory glycoprotein antibody that regulates the physiological balance between commensal intestinal bacteria and the defenses of the host immune system. It prevents the commensal microorganisms from invading the intestines.
