Fas ligand with improved stability providing significantly enhanced immune activation. Alternative name: FasL (oligomer), APO-1L (oligomer), CD95L (oligomer), CD178 (oligomer), TNFSF 6 (oligomer). MW: ~32kDa (nonglycosylated), ~35kDa (glycosylated). Concentration: 0.1mg/ml after reconstitution. Endotoxin content: <0.1EU/µg purified protein (LAL test; Associates of Cape Cod). Purity: ≥95% (SDS-PAGE). Formulation: Lyophilized. Contains PBS. 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 rhs SUPERFASLIGAND is similar to natural human FasL. Specificity: Binds to human, mouse and rat Fas (CD95; APO-1). Use/Stability: Stable for at least 6 months after receipt when stored at -20°C. UniProt: P48023. Application: ELISA. Handling: Avoid freeze/thaw cycles. After reconstitution, prepare aliquots and store at -20°C. Long Term Storage: -20°C
