| Product name | Recombinant Human Transferrin/TF Protein |
|---|---|
| Catalog No. | RP00997 |
| Description | Recombinant Human Transferrin/TF Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Val20-Pro698) of human Transferrin (Accession #NP_001054.1) fused with a 6×His tag at the C-terminus. |
| Bio-Activity | 1.Measured in a serum-free cell proliferation assay using MCF-7 human breast cancer cells. The ED50 for this effect is 0.075-0.3 ng/mL. 2.Measured by its binding ability in a functional ELISA. Immobilized Recombinant human Transferrin at 2 μg/mL (100 μL/well) can bind Recombinant human TfR with a linear range of 4-17 ng/mL. |
| Purity | > 97% by SDS-PAGE. |
| Endotoxin | < 0.1 EU/μg of the protein by LAL method. |
| Formulation | Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation. |

| Storage | Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week. |
|---|---|
| Reconstitution | Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles. |
