Background
Tumor necrosis factor receptor superfamily member 4 (TNFRSF4) is also known as ACT35 antigen, OX40L receptor, TAX transcriptionally-activated glycoprotein 1 receptor, CD antigen CD134, OX40. OX40 / TNFRSF4 contains four TNFR-Cys repeats. TNFRSF4 is receptor for TNFSF4 / OX40L / GP34 and can interacts with TRAF2, TRAF3 and TRAF5
Source
Recombinant Mouse OX40, Fc Tag (OX0-M5259) is expressed from human 293 cells (HEK293). It contains AA Val 20 - Pro 211 (Accession # NP_035789).
Predicted N-terminus: Val 20
Molecular Characterization
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 47.9 kDa. The protein migrates as 55-70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method.
Purity
>90% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.
Reconstitution
