TPO HEK Recombinant eiwit

Source : HEK. Thrombopoietin Human Recombinant produced in HEK cells is a glycosylated monomer, having a molecular weight range of 80-85kDa due to glycosylation.The TPO is purified by proprietary chromatographic techniques. Thrombopoietin is a glycoprotein hormone produced mainly by the liver and the kidney that regulates the production of platelets by the bone marrow. It stimulates the production and differentiation of megakaryocytes, the bone marrow cells that fragment into large numbers of platelets.

Greater than 90% as obsereved by SDS-PAGE.

The TPO protein was lyophilized from 1mg/mL in 1xPBS.

Lyophilized Thrombopoietin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TPO should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA) .Please prevent freeze-thaw cycles.

It is recommended to reconstitute the lyophilized Thrombopoietin in sterile PBS containing 0.1% endotoxin-free recombinant HSA. The activity was determined by the dose-dependent stimulation of the proliferation of MO7e cells, the EC50 is 3.8ng/ml.
