内毒素:

Less than 1.0 EU per μg by the LAL method.



纯度:

>95% as determined by SDS-PAGE.



活性:

Measured by its binding ability in a functional ELISA. Immobilized Anti-OX40 MAb, Human IgG1 at 2 μg/mL (100 μL/well) can bind Biotinylated Human OX40, His Tag (Catalog # TN4-H82E4) with a linear range of 1-5 ng/mL.



产品背景:

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.



产品描述:

This protein carries an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag. The protein has a calculated MW of 22.8 kDa. The protein migrates as 40-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
SDS-PAGE


Biotinylated Human OX40 / TNFRSF4 / CD134, His Tag on SDS-PAGE  under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
