產品描述
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.
產品性質
別名（Synonyms） | CD137; TNFRSF9; 4-1BB ligand receptor; 41BB; 4-1BB; CDw137; FLJ43501; ILA; T cell antigen ILA |
Uniprot No. | Q07011 |
表達區間及表達系統（Source） | HEK293 Cells-derived Human 4-1BB/TNFRSF9 Protein, Leu24-Gln186 with His tag at the C-terminal |
分子量(Molecular Weight) | Approximately 18.1 kDa. Due to glycosylation, the protein migrates to 35-40 kDa based on Tris-Bis PAGE result. |
外觀(Physical Appearance） | Sterile Filtered White lyophilized (freeze-dried) powder. |
純度（Purity） | > 95% as determined by SDS-PAGE and HPLC |
活性（Activity） | ELISA Data: Immobilized Human 4-1BB, His Tag at 1μg/mL (100 μL/Well) on the plate. Dose response curve for Human 4-1BB Ligand Trimer, hFc Tag with the EC50 of 5.7 ng/mL determined by ELISA. |
內毒素（Endotoxin） | < 1.0 EU per 1μg of the protein by the LAL method. |
制劑（Formulation） | Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
復溶（Reconstitution） | Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water. |
運輸與保存方法
