Human TRAIL Transfected Cell Line

简单描述

The RIK-2 monoclonal antibody specifically binds to CD253, also known as TRAIL (TNF-Related Apoptosis-Inducing Ligand) and Apo2 ligand (APO-2L). CD253 is a member of the Tumor Necrosis Factor Superfamily and is encoded by the TNFSF10 gene. CD253 is a type II membrane protein that may be expressed as a soluble as well as full-length, cell surface-associated protein. Both surface and soluble forms of TRAIL rapidly induce apoptosis in a wide range of tumor cell lines but not normal tissue. TRAIL is expressed by activated T cells, NK cells, dendritic cells, monocytes and a variety of non-lymphoid cells. TRAIL can bind to and exert apoptosis through DR4 (TRAIL-R1) and DR5 (TRAIL-R2) receptors. It can also bind to decoy receptors, including DcR1/TRID/TRAIL-R3 and DcR2/TRUNDD/TRAIL-R4, and possibly OPG/TNFRSF11B, which may serve to regulate TRAIL activity. TRAIL has been shown to be involved in T cell-mediated cytotoxicity, but its mechanism of action remains to be fully elucidated. The RIK-2 clone was selected based on its ability to block TRAIL-mediated cytotoxic activity.

NA/LE

NA/LE refers to the culture and purification methods and buffer used to produce purified antibodies with no azide and low endotoxin: Aqueous buffered solution containing no preservative, 0.2µm sterile filtered. Endotoxin level is ≤0.01 EU/µg (≤0.001 ng/µg) of protein as determined by the LAL assay.NA/LE are perfectly suited to be used in culture or in vivo (for nonhuman studies) for functional assays — blocking, neutralizing, activation or depletion — where the presence of azide may damage cells or exogenous endotoxin may signal or activate cells.

Flow Cytometric Analysis of TRAIL-induced Killing and RIK-2 Blocking using FITC Annexin V staining. Jurkat T cells were left untreated (far left/first panel) or treated for 16 hours under the following conditions: Cells were incubated with 20 ng/ml of recombinant human TRAIL and 10 µg/ml anti-histidine antibody (second panel); or with 20 ng/ml of recombinant human TRAIL and 10 µg/ml anti-histidine antibody preincubated with RIK-2 antibody (third panel); or with 20 ng/ml of recombinant human TRAIL and 10 µg/ml anti-histidine antibody preincubated with mIgG1 antibody (negative control) (far right/fourth panel). Following treatments, cells were evaluated for Annexin-V staining. Cells induced to undergo apoptosis by treatment with recombinant human TRAIL gave a population of cells that was Annexin V-FITC positive (second panel, M2). Annexin V-FITC staining was blocked when cells were incubated with a mixture of recombinant human TRAIL and RIK-2 antibody (third panel, M2). Cells treated with the mixture of recombinant TRAIL and mIgG1 antibody could not block the killing (far right/fourth panel). A small number of Annexin-V positive cells in the untreated population represents a basal level of apoptosis (far left/first panel). The results indicate that clone RIK-2 can block cell mediated killing induced by recombinant human TRAIL as measured by Annexin V-FITC staining of Jurkat cells.
