4-1BB/TNFRSF9, His, Human

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.

产品简介
Species Human
Protein Construction
4-1BB/TNFRSF9 (Leu24-Gln186)
Accession # Q07011		 His
N-term C-term
Purity > 95% as determined by Bis­Tris PAGE 
> 95% as determined by HPLC
Endotoxin Level Less than 1EU per μg by the LAL method.
Biological Activity Measured by its binding ability in a functional ELISA. Immobilized 4-1BB/TNFRSF9, His, Human at 1μg/ml (100μl/Well) on the plate can bind Human 4­1BB Ligand Trimer, hFc Tag. Test result was comparable to standard batch.
Expression System HEK293
Theoretical Molecular Weight 18.1 kDa
Apparent Molecular Weight Due to glycosylation, the protein migrates to 35-40 kDa based on Bis-Tris PAGE result.
Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4).
Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage & Stability Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles.
