Description

Immunogen

Purified mouse IgA

Preparation Note

Prepared using the periodate method described by Wilson, M.B., and Nakane, P.K., in Immunofluorescence and Related Staining Techniques, Elsevier/North Holland Biomedical Press, Amsterdam, p 215 (1978).

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 0.01% thimerosal.

Application

Anti-mouse IgA (α-chain specific)-peroxidase antibody can be used in modified indirect DIBA (dot- immunobinding assay) 1.

ELISAS were performed using HRP conjugated gaot anti-mouse IgA as the secondary antibody at a dilution of 1:10000 for a 1 hour incubation at 37 degrees to detect IgA levels in mouse fecal extracts.

General description

IgA antibody plays an essential role in mucosal immunity and binds with immunogens/pathogens to restrict them from entering the mucosal membrane2. Anti-mouse IgA (α-chain specific)-peroxidase antibody can be used for determining the secretory IgA (sIgA) in intestinal fluid3. It can also be used in direct ELISA. Goat anti-mouse IgA (α-chain specific)-peroxidase antibody reacts specifically with mouse IgA.
