TRAIL, soluble, Recombinant, Human (TRAIL, Apo-2L, TNFSF10, CD253)

TNF-related apoptosis-inducing ligand (TRAIL, Apo2L,CD253, TNFSF10) is a type II transmembrane protein of about 34kD. Like most members of the tumor necrosis factor (TNF) superfamily of cytokines TRAIL can be cleaved at the cell surface by metalloproteases to form a soluble molecule. Active TRAIL forms trimers and specifically binds to fi ve distinct receptors: TRAIL-R1 (DR4, Apo2,CD261, TNFRSF10A), TRAIL-R2 (DR5, KILLER, TRICK2A,TRICK2B, CD262, TNFRSF10B), TRAIL-R3 (DcR1,LIT, TRID, CD263, TNFRSF10C), TRAIL-R4 (DcR2,TRUNDD, CD264, TNFRSF10D), and osteoprotegerin (OPG, OCIF, TNFRSF11B). Trimerized TRAIL triggers apoptosis upon ligation of cell surface TRAIL-R1 and/or TRAIL-R2 by inducingthe formation of the so-called multiprotein death-inducing signaling complex (DISC). Biological Activity: Induces apoptosis in a concentration range of 10-100ng/ml. Note: Does not require a cross-linking enhancer for its potent biological activity. ED50: 20ng/ml (BJAB cells). Sequence: The extracellular domain of human TRAIL (aa 95-281) is fused at the N-terminus to a His-tag and a linker peptide. Storage and Stability: Short-term Storage: -20°C, Long-term Storage: -80°C
