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 Human OX40 Protein, His Tag (MALS verified) (OX0-H5224) is expressed from human 293 cells (HEK293). It contains AA Leu 29 - Ala 216 (Accession # P43489-1).
Predicted N-terminus: Leu 29
Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 22.0 kDa. The protein migrates as 35-45 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 PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
Reconstitution
Please see Certificate of Analysis for specific instructions.
For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.
Storage
