Description

General description

IgA is the highest generated antibody isotype. IgAs are mainly secreted in the intestinal mucosa.
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.

Specificity

The antibody preparation is specific for human IgA when tested against purified human IgA, IgG, IgM, Bence Jones kappa and lambda myeloma proteins.

Immunogen

IgA purified from normal human colostrum

Application

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)

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide as preservative

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing, or storage in "frost-free" freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.

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.
