Human CD178 ELISpot Pair

CD178, also called Fas Ligand (FasL) or TNFSF6, is a type II transmembrane protein of the tumor necrosis factor family that initiates apoptosis through engagement of the Fas (CD95) receptor on target cells. The Assay Genie Human CD178 ELISpot Pair delivers matched capture and detection antibodies in a single-use vial format, enabling researchers to enumerate FasL-secreting cells at single-cell resolution from cell culture supernatants and serum. This cell-based immunoassay supports functional studies of cytotoxic T lymphocyte and NK cell effector activity, tumor immune evasion, autoimmune mechanisms, and peripheral tolerance. The pair is intended for research use only and is suited to a microplate workflow in immunology, transplantation, and oncology laboratories, where it complements flow cytometry and intracellular staining approaches for characterizing antigen-specific effector populations.
