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.

Description: Recombinant Human OX40 Ligand is produced by our Mammalian expression system and the target gene encoding Gln51-Leu183 is expressed with a mFc tag at the C-terminus.

Alternate Names: Tumor necrosis factor ligand superfamily member 4, Glycoprotein Gp34, OX40 ligand, OX40L, TAX transcriptionally-activated glycoprotein 1, TNFSF4, CD252, TXGP1

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

Biological Activity: Immobilized Human OX40-Fc (Cat#CK58) at 8μg/ml (100 μl/well) can bind Human OX40L-mFc (Cat#CW25) .The ED50 of Human OX40L-mFc (Cat#CW25) is 18.54 ng/ml.

Redissolve: Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. 

Endotoxin: Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.

Molecular Weight: 42.2 KDa

Observed Molecular Weight: 50-70 KDa, reducing conditions

Storage: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
