分子别名(Synonym)

OX40L,TNFSF4,CD252,Glycoprotein Gp34,TXGP1

表达区间及表达系统(Source)

Human OX40 Ligand, Fc Tag (OXL-H526x) is expressed from human 293 cells (HEK293). It contains AA Gln 51 - Leu 183 (Accession # NP_003317).

Predicted N-terminus: Gly

蛋白结构(Molecular Characterization)

Unconjugated(Gln 51 - Leu 183) NP_003317

This protein carries a human IgG1 Fc tag at the N-terminus.

The protein has a calculated MW of 42.9 kDa. The protein migrates as 53-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

背景(Background)

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.
