Recombinant Human Thrombopoietin (TPO) is a bioactive protein intended for use in cell culture applications. TPO is a humoral growth factor that is necessary for megakaryocyte proliferation and maturation, as well as for thrombopoiesis. This protein is the ligand for MLP/C_MPL, which is the product of the myeloproliferative leukemia virus oncogene. Recombinant Human Thrombopoeitin (TPO) is one of the many GIBCO® recombinant bioactive proteins available from Life Technologies. This is the 10 milligram size.

High purity recombinant bioactive protein
Recombinant Human Thrombopoietin (TPO) is one of more than 250 GIBCO® recombinant proteins available from Life Technologies. To help ensure GIBCO® growth factors are of the highest quality, each protein is analyzed for purity along with structural homogeneity to help ensure a biologically active protein.

High biological activity
In-house activity testing of Recombinant Human Thrombopoeitin (TPO) includes cell proliferation, cytotaxis, calcium flux, secondary cytokine up-regulation, induction of surface antigen expression, and protease assays. Recombinant Human Thrombopoietin (TPO) specific activity is determined by the dose-dependent stimulation of the proliferation of human TF-1 cells (human erythroleukemic indicator cell line).
