> 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 TNFR2/CD120b/TNFRSF1B, His, Cynomolgus at 1μg/ml (100μl/Well) on the plate can bind AntiTNFR2 Antibody, hFc Tag. Test result was comparable to standard batch. |
| Expression System |
HEK293 |
| Theoretical Molecular Weight |
26.1 kDa |
| Apparent Molecular Weight |
Due to glycosylation, the protein migrates to 49-60 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. |
| Target Background |
Tumor Necrosis Factor Receptor II (TNF RII), also known as TNFRSF1B, p75/p80, and CD120b, is a type I transmembrane protein that belongs to the TNF receptor superfamily. It has a molecular weight of approximately 75 kDa.Receptor with high affinity for TNFSF2/TNF-alpha and approximately 5-fold lower affinity for homotrimeric TNFSF1/lymphotoxin-alpha. The TRAF1/TRAF2 complex recruits the apoptotic suppressors BIRC2 and BIRC3 to TNFRSF1B/TNFR2. This receptor mediates most of the metabolic effects of TNF-alpha. Isoform 2 blocks TNF-alpha-induced apoptosis, which suggests that it regulates TNF-alpha function by antagonizing its biological activity. |
