Bovine Secretory Immunoglobulin A (sIgA) ELISA Kit

Quantify bovine secretory immunoglobulin A (sIgA) concentrations in cattle-derived specimens with this colorimetric ELISA kit from Assay Genie. The assay targets sIgA, the dominant antibody isotype secreted across mucosal surfaces in cattle, and is intended for research use only in veterinary immunology, mucosal vaccine response studies, and investigations of passive immunity transfer in calves via colostrum. Sample matrices compatible with the assay include serum or plasma specimens and saliva from cattle, supporting studies ranging from respiratory and gastrointestinal mucosal defense to udder health research in dairy herds. The kit is supplied in a 96-assay format with all reagents required to generate a standard curve and run unknown samples in parallel. Store the components refrigerated on arrival and avoid repeated freeze-thaw cycles of working standards to preserve immunoreactivity.
