Biotinylated Human 4-1BB/TNFRSF9 Protein
Recombinant Biotinylated Human 4-1BB/TNFRSF9 Protein is expressed from HEK293 with hFc tag and Avi tag at the C-Terminus.It contains Leu24-Gln186 [Accession | Q07011].
The protein has a predicted MW of 45.7 kDa. Due to glycosylation, the protein migrates to 60-70 kDa based on Bis-Tris PAGE result.
> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC
Less than 1EU per μg by the LAL method.
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-20 to -80°C for 24 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

The purity of Biotinylated Human 4-1BB is greater than 95% as determined by SEC-HPLC.
Immobilized Biotinylated Human 4-1BB , hFc Tag at 1μg/ml (100μl/well) on the streptavidin precoated plate (5μg/ml). Dose response curve for Human 4-1BB Ligand (Trimer) , His Tag with the EC50 of 14.5ng/ml determined by ELISA.
4-1BB, is also known as CD137, is a type 2 transmembrane glycoprotein receptor belonging to the TNF superfamily.CD137 can be expressed by activated T cells, but to a larger extent on CD8 than on CD4 T cells. In addition, CD137 expression is found on dendritic cells, B cells, follicular dendritic cells, natural killer cells, granulocytes and cells of blood vessel walls at sites of inflammation.
