产品描述

General description

Fas Ligand (FasL) is a member of the TNF (tumor necrosis factor) superfamily that is expressed on the cell surface of activated T cells.[2][3] It can be present as soluble form in the circulation or membrane bound form in cells.[5] Recombinant human soluble Fas Ligand is a 17.9kDa protein comprising the TNF homologous region of FasL and contains an 8 residue N-terminal His-Tag. Both human and murine sFasL are fully active on human and murine cells.

Application

Fas ligand human has been used to induce apoptosis in T-cell lymphoma-derived HuT78 cells and jurkat cells.[9]

Biochem/physiol Actions

Binding of Fas Ligand (FasL) to Fas receptor triggers apoptosis in Fas-bearing cells. FasL has the ability to kill T cells and activated B cells which leads to down-regulation of the immune response.[3][4] The mechanism of Fas induced apoptosis involves recruitment of pro-caspase 8 through an adaptor molecule called FADD (Fas-Associated protein with death domain) followed by processing of the pro-enzyme to active forms. These active caspases then cleave various cellular substrates leading to the eventual cell death. FasL is also involved in AGE (advanced glycation end-product)-mediated apoptosis in human retinal ARPE-19 cells, suggesting its role in diabetic retinopathy.[1] Changes in the activity of FasL suppresses normal apoptosis, leading to abnormal survival and growth of tumor cells.[6] Mutations in the FasL gene causes autoimmune lymphoproliferative syndrome.

Physical form

Lyophilized with no additives.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
