Recombinant Human TNFSF15 Protein

Product Name: Recombinant Human TNFSF15 Protein
Catalog #:  HRP-1042
Manufacture:  LD Biopharma, Inc.

The protein encoded by human tumor necrosis factor ligand superfamily member 15 (TNFSF15) gene is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This protein is abundantly expressed in endothelial cells, but is not expressed in either B or T cells. The expression of TNFSF15 protein is inducible by TNF and IL-1 alpha. This cytokine is a ligand for receptor TNFRSF25 and decoy receptor TNFRSF21/DR6. It can activate NF-kappaB and MAP kinases, and acts as an autocrine factor to induce apoptosis in endothelial cells. This cytokine is also found to inhibit endothelial cell proliferation, and thus may function as an angiogenesis inhibitor. Two transcript variants encoding different isoforms have been found for this gene.

Full-length extracellular domain of human TNFSF15 cDNA (57 - 251 aa, Isoform VEGI-251, derived from BC074941) was constructed with codon optimization and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal and expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
