Description | Recombinant of human TNFR2 protein |
Form/Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Purity | Greater than 97.0% as determined by SDS-PAGE. |
Solubility (25°C) | It is recommended to reconstitute the lyophilized TNFR2 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |

Source | Escherichia Coli |
Biological Activity | The ED50 as determined by its ability to inhibit the TNF-a mediated cytotoxicity in the L-929 cells is less than 0.2µg/ml, corresponding to a specific activity of > 5000IU/mg in the presence of 0.25ng/mL of rHuTNF-a. |
Storage | Stability: Lyophilized TNFR2 although stable at room temperature for 3 weeks, should be stored desiccated below -1°C. Upon reconstitution TNFR2 should be stored at 4C between 2-7 days and for future use below -1°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles |
Buffer/Preservatives | TNFR2 was Lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4. |

The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining. | |
The protein has a predicted molecular mass of 51.3 kDa after removal of the signal peptide. The apparent molecular mass of TNFRSF1B-hFc is approximately 55-70kDa due to glycosylation. | |
Mammalian |
> 95% as determined by Tris-Bis PAGE; > 95% as determined by SEC-HPLC | |
Due to glycosylation, the protein migrates to 65-75 kDa based on Tris-Bis PAGE result. |
The purity of the protein is greater than 85% as determined by SDS-PAGE and Coomassie blue staining. | |
The protein has a predicted molecular mass of 26.0 kDa after removal of the signal peptide. The apparent molecular mass of TNFRSF1B-His is approximately 35-55 kDa due to glycosylation. | |
