TRAIL Receptor-1/DR4 and TRAIL Receptor-2/DR5 belong to the TNFR superfamily of transmembrane proteins and contain a cytoplasmic death domain, which can activate the cells apoptotic machinery. These receptors are activated by binding to either membrane anchored or soluble TRAIL/Apo2L. Recombinant human soluble TRAIL Receptor-1/DR4 is a 22.7 kDa protein (215 amino acid residues) consisting of the TNFR homologous, cysteine rich portion of the extracellular domain. Biological Activity: The specific activity as determined by its inhibitory effect of IL-8 production in human PBMC (peripheral blood mononuclear cells) by human sTRAIL/Apo2L. 95% inhibition (100ng/ml of sTRAIL/Apo2L) was reached using a concentration of 100ng/ml of sTRAIL Receptor-1.
