Human KIR3DX1 ELISA Kit (HUFI07731)

The Assay Genie Human KIR3DX1 ELISA Kit enables quantitative measurement of this X-chromosome-encoded member of the killer-cell immunoglobulin-like receptor family in human research samples. KIR3DX1 is a three-Ig-like domain receptor increasingly studied in NK cell and T cell immunology, particularly in contexts of reproductive immunity, infection response, and tumor surveillance. Each kit is supplied as a complete microplate assay with all reagents required for capture and readout, including pre-coated wells, detection antibody, reference standards, and substrate solution. Standards should be refrigerated on arrival; for longer storage, aliquot and freeze to preserve activity and limit freeze-thaw cycles. The kit is intended for research use only and supports in vitro studies of KIR gene expression in immune cell research. Researchers investigating maternal-fetal immune tolerance, NK cell licensing, or KIR diversity in disease cohorts will find this a useful addition to their immunophenotyping workflow.
