Human OX40/TNFRSF4 PharmaGenie ELISA Kit (SBRS0959)

Quantitative measurement of human OX40/TNFRSF4 (also known as CD134) in cell culture supernatant, plasma, and serum samples is supported by this Assay Genie PharmaGenie ELISA Kit. OX40 is a costimulatory receptor expressed primarily on activated T cells, and its quantification is used in immunology and oncology research, particularly in studies of checkpoint pathways and therapeutic antibody development.

The kit produces a colorimetric signal readable on standard plate readers, and the assay is supplied as a complete microplate kit with all reagents needed to run a full plate. Each well is pre-coated with capture antibody, and the workflow follows a standard immunoassay format with sample addition, biotinylated detection antibody binding, and substrate development. Researchers studying T-cell activation, immune checkpoint biology, or the pharmacodynamics of OX40-targeting therapeutics can use this kit to generate reproducible concentration data across experiments. The plate contains sufficient reagents for a full run, and the kit is intended for research use only.
