Product Details

Alternative Name:CD95, APO-1, TNFRSF 6
MW:~56 kDa
Source:Produced in HEK 293 cells. The extracellular domain of human Fas (CD95; APO-1) (aa 7-154) is fused to the Fc portion of human IgG1.
UniProt ID:P25445
Concentration:1mg/ml after reconstitution.
Formulation:Lyophilized. Contains PBS.
Purity:≥95% (SDS-PAGE)
Purity Detail:Purified by multi-step chromatography.
Endotoxin Content:<0.1EU/µg purified protein (LAL test; Associates of Cape Cod).
Species reactivity:Human, Mouse, Rat
Specificity:Binds human, mouse and rat FasL (APO-1L; CD95L; CD178).
Application Notes:ELISA: binds to FasL at 10-100 ng/ml.
Reconstitution:Reconstitute with 50µl sterile water. Further dilutions can be made with medium containing 5% fetal calf serum or a carrier protein.
Shipping:Blue Ice
Long Term Storage:-20°C
Use/Stability:Stable for at least 6 months after receipt when stored at -20°C.
Handling:Avoid freeze/thaw cycles. After reconstitution, prepare aliquots and store at -20°C.
Technical Info/Product Notes:Historical data has shown that Fas inhibits the activity of human and mouse soluble Fas (sFasL) and thereby sFasL-mediated lysis of Fas sensitive cells in a concentration range of 20-100µg/ml. When used with cross-linking enhancer (see Prod. No. ALX-203-001), the inhibitory activity of rhFas:Fc is increased approximately 20- to 50-fold. Concentrations of rhFas:Fc required to inhibit may vary depending on the cell viability and on the concentrations of sFasL used to kill the cells.
Regulatory Status:RUO - Research Use Only

Figure: Inhibition of FasL, Soluble (human) (rec.) (Prod. No. ALX-522-001)-mediated lysis. Fas (human):Fc (human) (rec.) (Prod. No. ALX-522-002) exerts its inhibitory activity in a concentration range of 0.5-5µg/ml in the presence of the enhancer (1µg/ml).Method: Mouse A20 B lymphoma cells (50’000 cells in 100µl DMEM medium containing 5% fetal calf serum) were incubated with 0.2µg/ml FasL, Soluble (human) (rec.) and increasing concentrations of Fas (human):Fc (human) (rec.) in the presence and the absence of 1µg/ml enhancer) in a 96-well plate for 16 hours at 37°C. Concentrations of Fas (human):Fc (human) (rec.) required to inhibit may vary depending on the cell type studied and on the concentration of rhsFasL used to kill cells. Cell viability was determined using an MTT-based cell proliferation assay kit."
