Rat Secretory Immunoglobulin A (sIgA) ELISA Kit

The Assay Genie rat secretory IgA immunoassay delivers quantitative measurement of secretory immunoglobulin A across rat-derived specimens, supporting mucosal immunology research where sIgA serves as a biomarker of mucosal barrier integrity, gut-associated lymphoid tissue activity, and local humoral defense at respiratory, gastrointestinal, and reproductive surfaces.

Each kit contains a pre-coated microplate, calibration standards, detection reagents, and buffer solutions required to evaluate sIgA concentrations in rat-origin samples. The plate-based colorimetric readout is captured on a standard plate reader, with a standard curve generated in parallel for each run to interpolate unknown values. Researchers studying mucosal vaccination, infection challenge, dietary intervention, or pharmacological manipulation in rat disease models can use this kit to track sIgA dynamics over the course of an experiment. Reconstituted reagents should be aliquoted and stored frozen to preserve activity across freeze-thaw cycles, and the kit should be refrigerated upon arrival to preserve reagent integrity.

Intended for research use only, the assay helps laboratories characterize secretory antibody responses in translational rat models relevant to human mucosal disease, vaccine development, and microbiome investigations.
