Beschreibung

Allgemeine Beschreibung

Recombinant, human, Fas ligand consisting of amino acids 103-281 fused at the N-terminus to a tag-linker peptide. Binds to human, mouse, and rat Fas. The recombinant protein is produced in HEK293 cells. Useful for cytotoxicity assays.



Fas/APO1/CD95 (37-42 kDa), a member of the Tumor Necrosis Factor/Nerve Growth Factor (TNF/NGF) receptor family, is an apoptosis-signaling surface receptor known to trigger apoptotic cell death. Homology exists between the Fas and TNF receptors including a region called the "death domain" which is required to propagate the apoptotic signal. The signal activates a family of cysteine proteases, or caspases, which systematically lead to cell destruction. Genetic defects in the Fas system have been shown to lead to autoimmune disorders while increased activity or deregulation contributes to the pathology of diseases such as AIDS.

Recombinant, human, Fas ligand consisting of amino acids 103-281 fused at the N-terminus to a tag-linker peptide. Binds to human, rat, and mouse Fas.The recombinant human soluble Fas ligand recognizes the Fas receptor in human, rat and mouse. Extracellular domain of human FasL, 103 - 281 fused at the N-terminus to a tag linker peptide.

The soluble Fas ligand kills APO-1/Fas-sensitive cells at a concentration of >50 ng/ml. For example, cell death results when 5 x 10⁵ murine A20 B lymphoma cells are incubated with 50-500 ng/ml of the recombinant human soluble APO1/FasL (aa 103-281) for 16 h at 37°C.
