  • Function
    Cytokine that binds to TNFRSF6/FAS, a receptor that transduces the apoptotic signal into cells. May be involved in cytotoxic T-cell mediated apoptosis and in T-cell development. TNFRSF6/FAS-mediated apoptosis may have a role in the induction of peripheral tolerance, in the antigen-stimulated suicide of mature T-cells, or both. Binding to the decoy receptor TNFRSF6B/DcR3 modulates its effects.
  • Involvement in disease
    Defects in FASLG are the cause of autoimmune lymphoproliferative syndrome type 1B (ALPS1B) [MIM:601859]; also known as Canale-Smith syndrome (CSS). ALPS is a childhood syndrome involving hemolytic anemia and thrombocytopenia with massive lymphadenopathy and splenomegaly.
  • Sequence similarities
    Belongs to the tumor necrosis factor family.
  • Post-translational
    The soluble form derives from the membrane form by proteolytic processing.
  • Cellular localization
    Cell membrane. Secreted. May be released into the extracellular fluid, probably by cleavage form the cell surface.

For stimulation, 1 µg/ml of PMA (Sigma, P1585) and 5 µg/ml of Ionomycin (Sigma, I0634) were added to cells and incubated for 2 hours. For the last 30 minutes of this 2 hour incubation, 0.1mM of 10PM (I, 10- Phenanthroline Monohydrate) ...

The final concentration of 10PM should be around 0.1mM. The 1µg/mL of PMA and 5µg/mL of Ionomycin are the final concentrations in the cell supsension. Also, when adding 10PM, add it in the last thirty minutes of the 2 hour stimulation.

While we believe that this product will work with soluble Fas Ligand, we have not tested this antibody to confirm.

The protocol for the positive control for flow cytometry is given below:

1 µg/ml of PMA (Sigma, P1585) and 5 &mic...
