| Formulation |
TPO protein solution (0.25mg/ml) contains phosphate buffered saline (pH7.4) and 10% glycerol. |
| Purity |
Greater than 85% as determined by SDS-PAGE. |
| Description |
TPO produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 340 amino acids (22-353aa.) and having a molecular mass of 36.5kDa. (Molecular size on SDS-PAGE will appear at approximately 40-57KDa).TPO is expressed with an 8 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.. |
| Protein Background |
Thrombopoietin is a glycoprotein hormone produced mainly by the liver and the kidney which regulates the production of platelets by the bone marrow. TPO stimulates the production as well as differentiation of megakaryocytes, the bone marrow cells which fragment into large numbers of platelets. |
| Expression host |
Sf9, Insect cell. |

| Reagent Appearance |
Sterile Filtered clear solution. |
| Stability |
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles. |
