Human SAG ELISA Kit (HUFI06669)

The SAG protein, also known as S-arrestin or arrestin-1, plays a critical role in terminating light-induced signaling within retinal photoreceptor cells. This Assay Genie immunoassay supports quantitative research on S-antigen levels in human clinical samples, with applications in autoimmune retinopathy, cancer-associated retinopathy (CAR), and paraneoplastic ocular syndrome investigations.

The kit ships as a complete pack with a pre-coated well plate, biotinylated detection reagents, standards, streptavidin-HRP conjugate, and assay buffer components intended for laboratory research workflows. Reagents should be handled according to the enclosed protocol, with standard components kept refrigerated and protected from light to maintain activity through the stated shelf life. Researchers in ophthalmology, immunology, and oncology laboratories may use this kit when screening patient specimens for autoantibody-associated retinal disease biomarkers.
