Product Details

Alternative Name:APO-1L, CD95L, CD178, TNFSF 6
MW:~32kDa (non-glycosylated), ~35kDa (glycosylated) (SDS-PAGE).
Source:Produced in HEK 293 cells. The extracellular domain of human FasL (APO-1L; CD95L; CD178) (aa 103-281) is fused at the N-terminus to a linker peptide (26 aa) and a FLAG®-tag. Glycosylation of rhsFasL is similar to that of natural human FasL.
UniProt ID:P48023
Concentration:0.1mg/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 to human, mouse and rat Fas (CD95; APO-1).
Biological Activity:Kills Jurkat cells in the absence of a cross-linker. Cross-linking enhancer (see Set Prod. No. ALX-850-014) increases the activity of rhsFasL approx. 50-fold.
Attention: Results using sFasL may differ from those obtained with agonistic antibodies!
Application Notes:ELISA: binds to Fas receptor at 1-100 ng/ml.
Reconstitution:Reconstitute with 100µl sterile water. Further dilutions should be made with medium containing 5% fetal calf serum.
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 lots have shown that FasL kills Jurkat cells at concentrations of >10ng/ml in the absence of a cross-linker. Historical lots have also shown an ED50 of 50ng/ml (A20 cells).
Regulatory Status:RUO - Research Use Only
FasL (soluble) (human), (recombinant) Activity assay
Activity Assay analysis: 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).
