TNFSF15, Recombinant, Human (Tumor Necrosis Factor Ligand Superfamily Member 15, TNF Ligand-related

TL-1A belongs to the TNF superfamily of ligands. It is expressed predominantly in endothelial cells, and to a lesser extent in placenta, lung, kidney, skeletal muscle, pancreas, small intestine and colon. TL-1A inhibits endothelial cell proliferation and angiogenesis, and has been shown to induce NFkB activation, caspase activity, and apoptosis in responding cell lines. TL-1A interacts with TNFRSF25/DR3 receptor, but can also bind to a decoy receptor TNFRSF21/DR6. Recombinant human TL-1A is a 22kD polypeptide of 194aa. Source: Recombinant protein corresponding to human TL-1A, expressed in E.coli. Biological Activity: Determined by its ability to stimulate IFN-gamma production by human PBMC using a concentration range of 10-100ng/ml. Note: Results may vary with PBMC donors.
