Fas Ligand is a 40 kDa type II transmembrane protein belonging to the TNF superfamily. The specific receptor for Fas Ligand is Fas (CD95, Apo-1). Fas Ligand is predominantly expressed on activated T cells and natural killer cells, while Fas is expressed on various types of cells. The Fas/Fas Ligand system plays a crucial role in modulating immune responses by inducing cell specific apoptosis. Human Fas Ligand shares 81% sequence identity with mouse Fas Ligand and 78% sequence identity with rat Fas Ligand.

Product Summary:
The Quantikine Mouse Fas Ligand Immunoassay is a 4.5 hour solid-phase ELISA designed to measure mouse Fas Ligand in cell culture supernates, serum, and plasma. It contains NS0-expressed recombinant mouse Fas Ligand and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural mouse Fas Ligand{\f9\i showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring mouse Fas Ligand.
Precision:
Intra-Assay Precision (Precision within an assay)Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays)Three samples of known concentration were tested in separate assays to assess inter-assay precision.

Linearity:
To assess the linearity of the assay, six samples containing and/or spiked with high concentrations of mouse Fas Ligand in each matrix were diluted with Calibrator Diluent and then assayed.
