Human IgA/Immunoglobulin A ELISA Kit

This sandwich ELISA kit from Assay Genie is designed for the quantitative measurement of Immunoglobulin A (IgA) in human samples. The assay uses a double antibody sandwich format with colorimetric detection, offering high sensitivity for research applications.

The kit is reactive with human samples and is validated for use with serum, plasma, cell culture supernatant, cell or tissue lysates, and other liquid samples. Sensitivity is rated at 1.875 ng/mL, with a detection range of 3.125–200 ng/mL. Kit components should be stored at 2–8°C and remain stable for up to 12 months.

Immunoglobulin A plays a critical role in the immune system, particularly in mucosal immunity, and abnormal IgA levels have been associated with various autoimmune diseases, infections, and gastrointestinal disorders. The kit supports immunology research by enabling reproducible measurement of IgA as a biomarker of immune response and disease mechanisms.
