Anti-Human-IgA( α-chain specific) can detect human IgA in normal and pathological situations such as cancer or autoimmune diseases. It could also be used in quantitative ELISA.

Affinity chromatography using anti-human IgA antibody linked to agarose was performed to purify proteins from 2E9IgA1 transfectant cells.


IgA produced from transformed cell line of human Epstein-Barr virus.

Physical form

Suspension in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide

General description

IgA antibody plays an essential role in mucosal immunity; it has shown to bind immunogens/pathogens to restrict them from entering the mucosal membrane. The Anti-Human IgA (alpha-chain specific) product increases sensitivity to human IgA without cross-reactivity to other substances. Offering minimal interspecies cross reactivity to mouse or a rat, making it ideal for use in screening antibodies produced by a hybridoma cells containing a mouse or a rat immunoglobulins.
The antibody preparation is specific for human IgA when tested against purified human IgA, IgG, IgM, and kappa and lambda light chains. The product does not react with mouse or rat IgG as observed by Ouchterlony Double Diffusion (ODD), prior to agarose bead coupling.
