Fas ligand (FasL) is a type II transmembrane protein that belongs to the tumor necrosis factor (TNF) family. Fas ligand is a homotrimeric protein and signals through trimerization of FasR, which spans the membrane of the "target" cell. This trimerization usually leads to apoptosis, or cell death. Soluble Fas ligand is generated by cleaving membrane-bound FasL at a conserved cleavage site by the external serine matrix metalloproteinase MMP-7. Soluble FasL is less active than their membrane-bound counterparts and do not induce receptor trimerization and DISC formation. FasL is regarded as a potential target for immunotherapy.1

IHC (NBF/Par.): This antibody should give satisfactory staining results when used at a concentration of 15 µg/ml. The recommended secondary antibody for IHC is PN:G505. For chromogenic detection with high signal and low background use PN:D100 or PN:K107.
Neutralization: This antibody is useful for neutralization of Human sFAS Ligand bioactivity. The antibody dose required to neutralize 50% (ND₅₀) of the biological activity of Human sFAS Ligand (at 2 ng/ml) is 2 - 8 µg/ml.

Goat Anti-Human Soluble Fas Ligand (sFAS Ligand) recognizes Human sFAS Ligand. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.
