Endotoxin Content |
<0.1EU/µg purified protein (LAL test; Bio Whittaker). |
Formulation |
Lyophilized. Contains PBS. |
MW |
~60kDa (reducing SDS-PAGE). |

≥95% (SDS-PAGE) |
Reconstitution |
Reconstitute with 50µl sterile water. Further dilutions should be made with medium containing 5% fetal calf serum or carrier protein. |
Source |
Produced in HEK 293 cells. The extracellular domain of human TNF-R1 (aa 1-211) is fused to the Fc portion of human IgG1. |
Specificity |
Binds human and mouse TNF-α (tumor necrosis factor-a). |
Technical Info / Product Notes |
Previous data has shown that TNF-R1 receptor binds to TNF-R1 and triggers various biological effects (including cell death). rhTNF-R1:Fc fusion protein blocks TNF-α-mediated lysis with a inhibitory activity in a concentration range of 10-50ng/ml using Wehi cells. |
