Human CD134 (OX40) (ACT35) is an activation-associated antigen which is predominantly expressed on activated CD4 positive cells. CD134 antigen is a member of the tumor necrosis factor (TNF) receptor family of molecules and may be involved with regulating T cell-dependent B cell proliferation and differentiation (2).
Molecular Structure: A soluble fusion protein consisting of the extracellular (177 aa) domain of mature extracellular human CD134 fused to murine IgG2a Fc (232 aa), with a predicted monomeric molecular weight of 45.6 kd.

Predicted monomeric molecular weight of 45.6 kd. Fusion construct is dimeric and runs at about 105 kd in non reduced SDS-PAGE.
Transfectant Cell Line: CHO
Functional Application: CD134-muIg fusion protein blocks binding of anti-human CD134 Ab and Recombinant CD252-muCD8 to human tumor cells. CD134-muIg has been used to dampen IFN gamma production by human benign prostate hyperplastic cells in vitro (6).
