Human Tumor Necrosis Factor Ligand Superfamily, Member 9 (TNFSF9) ELISA Kit

This in vitro ELISA-format immunoassay from Assay Genie quantifies Human Tumor Necrosis Factor Ligand Superfamily Member 9 (TNFSF9), the type II transmembrane ligand that engages the TNFRSF9 receptor to co-stimulate T-cell proliferation and cytokine secretion. The microplate-based format runs up to 96 determinations, supporting studies of tumor immunology, T-cell costimulatory signaling, and immune checkpoint biology where researchers track soluble 4-1BBL release from activated antigen-presenting cells. Each kit is refrigerated for cold-chain shipping and arrives with pre-coated strips, biotinylated detection reagent, lyophilized standard reference protein, wash concentrate, and substrate packaged in sealed vials. Researchers apply the workflow to cleared tissue lysates and conditioned medium from cultured immune cells, following the enclosed protocol to generate a standard curve and interpolate unknown concentrations against the recombinant calibrator.
