Human Secretory Immunoglobulin A ELISA Kit

Quantitative measurement of secretory immunoglobulin A (SIgA), the dominant antibody class in mucosal secretions, supports immunology research, vaccine studies, and infectious disease investigations. This Assay Genie laboratory kit enables the in vitro detection of human SIgA and is supplied in a 96 Assays configuration, providing microplate wells, capture antibodies, standards, and reagents for that number of determinations. Researchers studying mucosal barrier integrity, respiratory and gastrointestinal infection, allergy, and psychosocial stress-related immune changes commonly quantify SIgA in relevant human sample matrices.

The kit employs a quantitative immunoassay workflow with standard curve-based quantification, and the protocol can be completed in a standard wet-laboratory setting following the included instructions. Reagents should be stored refrigerated at 4°C, protected from light, and brought to room temperature before running the assay; aliquoting is recommended for repeated runs to minimize freeze-thaw cycles. Each kit includes the necessary coated plate, detection antibody, reference standards, and wash buffer for 96 Assays, supporting reproducible quantification of human SIgA concentrations in research samples for research use only.
