Validation Data Gallery

  • Purity of GMP-grade recombinant human TPO was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue.

  • GMP Recombinant human TPO (HZ-1248-GMP) stimulates dose-dependent proliferation of the MO7e (human megakaryoblastic leukemia) cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. MO7e cells under defined media conditions were treated with increasing concentrations of GMP recombinant TPO for 72 hours. The EC50 was determined using a 4-parameter non-linear regression model. Activity determination was conducted in triplicate on a validated bioassay. The EC50 range is 100-500 ng/mL​.

Background

TPO (Thrombopoietin) is a primary regulator of megakaryocyte development and platelet production in mammals. Human Thrombopoietin constitutively circulates and maintains thrombopoiesis through interaction with its cognate receptor, myeloproliferative leukemia protein(MPL). Thrombopoietin also plays an important role in the maintenance and regulation of hematopoietic stem cells (HSCs).
