CD253 (TRAIL) Monoclonal Antibody (RIK-2), PE, eBioscience™, Invitrogen™

Description

• Description: The RIK-2 monoclonal antibody reacts with human TNF-related apoptosis-inducing ligand (TRAIL), a member of the TNF superfamily
• TRAIL is not expressed by resting human cells but has been shown to be induced under certain activation conditions
• Iin addition it is expressed on several human tumor lines
• Interaction of TRAIL with its ligand, Apo-2, induces apoptosis
• RIK-2 blocks TRAIL-induced apoptosis
• Applications Reported: The RIK-2 antibody has been reported for use in flow cytometric analysis
• Applications Tested: The RIK-2 antibody has been pre-titrated and tested by flow cytometric analysis of human TRAIL transfected cells
• This can be used at 5 μL (0.06 μg) per test
• A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL
• Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test
• Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser
• Filtration: 0.2 μm post-manufacturing filtered
• TRAIL is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family
• TRAIL preferentially induces apoptosis in transformed and tumor cells, but does not appear to kill normal cells although it is expressed at a significant level in most normal tissues
• TRAIL binds to several members of TNF receptor superfamily including TNFRSF10A/TRAILR1, TNFRSF10B/TRAILR2, TNFRSF10C/TRAILR3, TNFRSF10D/TRAILR4, and possibly also to TNFRSF11B/OPG
• The activity of this protein may be modulated by binding to the decoy receptors TNFRSF10C/TRAILR3, TNFRSF10D/TRAILR4, and TNFRSF11B/OPG that cannot induce apoptosis
• The binding of TRAIL protein to its receptors has been shown to trigger the activation of MAPK8/JNK, caspase 8, and caspase 3
• Receptors for TRAIL include two death domain containing receptors, death receptor 4 (DR4) and DR5, as well as two decoy receptors, DcR1 and DcR2, lacking the intracellular signaling death domain
• TRAIL is a type II membrane protein and expressed in a variety of human tissues
• Like TNF and Fas ligand, TRAIL induces apoptosis and NF-kB activation in many tissues and cells.
