Background: Tumor necrosis factor ligand superfamily member 4(TNFSF4/OX40L) is a single-pass type II membrane protein.OX40L is expressed on the surface of activated B cells; T cells; dendritic cells and endothelial cells. OX40L binds to OX40 (CD134); a member of the TNF receptor superfamily that is expressed predominantly on activated CD4+ T cells. OX40-OX40L co-stimulates signal to promote the survival and proliferation of activated CD4+ T cells and prolong the immune response. It involved in T-cell proliferation and cytokine production. Additional; it has been found association with systemic lupus erythematosus; no association with occurrence of atherosclerosis.

Concentration:

Activity: Loaded Biotinylated Human OX40L-His on AR2G Biosensor, can bind Human OX40-Fc with an affinity constant of 70.3 nM as determined in BLI assay.

Sequence: Gln51-Leu183

Purity: > 95 % as determined by reducing SDS-PAGE.
