DR4 Antibody

Product Specifications

Background

DR4 Antibody: Apoptosis, or programmed cell death, occurs during normal cellular differentiation and development of multicellular organisms. Apoptosis is induced by certain cytokines including TNF and Fas ligand in the TNF family through their death domain containing receptors, TNFR1 and Fas. A novel death domain containing receptor was recently identified and designated DR4 (for death receptor 4) . The ligand for this novel death receptor has been identified and termed TRAIL, which is a new member in the TNF family. DR4 is also called TRAIL receptor-1 (TRAIL-R1) . DR4 is expressed in most of human tissues including spleen, peripheral blood leukocytes, small intestine and thymus. Like TNFR1, Fas and DR3, DR4 mediates apoptosis and NF-κ B activation in many tissues and cells.

Validation

KO Validation (Figure 1) : Anti-DR4 antibodies (1167) specificity was further verified by DR4 specific knockout cell lysate. DR4 signal was detected in wild type cells, but not in the DR4 knockout cells. KO Validation1167) Independent Antibody Validation in Cell lines (Figure 2) shows similar DR4 expression profile in human cell lines detected by two independent anti-DR4 antibodies that recognize different epitopes, 1139 against C-terminus domain and 1167 against the N-terminus domain. DR4 proteins are detected in all the tested cell lines except CaCo-2 at different expression levels by the two independent antibodies. Independent Antibody Validation in Cell lines1139 1167 KD validation (Figure 6, 10) : Anti-DR4 antibody specificity was further verified by DR4 specific siRNA knockdown. DR4 signal in SW480 and HeLa cells transfected with DR4 siRNAs was disrupted in comparison with that in cells transfected with control siRNAs. KD validation
