Receptor Assay
FACS assay shows that Biotinylated Human OX40, Avitag,His Tag (TN4-H82E4) can bind to HEK293/Human OX40 Ligand / TNFSF4 Stable Cell Line (CHEK-ATP054). HEK293/Human OX40 Ligand / TNFSF4 Stable Cell Line was red line, Negative control HEK293 cells was grey line (QC tested).

背景
Tumor necrosis factor ligand superfamily member 4 (TNFSF4) is also known as glycoprotein Gp34, OX40 ligand (OX40L), TAX transcriptionally-activated glycoprotein 1 and CD252, which belongs to the tumor necrosis factor family. TNFSF4 is the ligand for CD134 and is expressed on such cells as DC2s (a subtype of dendritic cells) enabling amplification of Th2 cell differentiation. The interaction of TNFSF4-TNFSF4 is involved in the pathogenesis of multiple autoimmune and inflammatory diseases such as systemic lupus erythematosus (SLE), carotid artery disease and cancer. Furthermore, similar to other TNF superfamily members, membrane-bound OX40 Ligand (TNFSF4) exists as a homotrimer. Human TNFSF4 shares 46% amino acid sequence identity with its mouse counterpart.
