IgA antibody plays an essential role in mucosal immunity and binds with immunogens/pathogens to restrict them from entering the mucosal membrane. Anti-mouse IgA (α-chain specific)-peroxidase antibody can be used for determining the secretory IgA (sIgA) in intestinal fluid. It can also be used in direct ELISA. Goat anti-mouse IgA (α-chain specific)-peroxidase antibody reacts specifically with mouse IgA.
Immunogen
Purified mouse IgA
Application
Anti-mouse IgA (α-chain specific)-peroxidase antibody can be used in modified indirect DIBA (dot- immunobinding assay) .
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.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin with preservative.
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).

The effect of Saccharomyces boulardii on the immune system was evaluated, comparing germ-free Swiss/NIH mice monoassociated with the probiotic with germ-free mice. Saccharomyces boulardii colonized the gut of germ-free mice and survived the gastrointestinal conditions. An increase in sIgA production
Immunoglobulin A is the most abundant immunoglobulin isotype in mucosal secretions. In this review, we summarize recent advances in our understanding of the sites, mechanisms and functions of intestinal IgA synthesis in mice. On the basis of these recent findings

Individuals with X-HIGM syndrome fail to express functional CD40 ligand; consequently they cannot mount effective protective antibody responses against pathogenic bacteria. We evaluated, compared, and characterized the humoral immune response of wild type (WT) and C57-CD40L deficient (C57-CD40L(-/-)) mice infected
