TPO/Thrombopoietin Protein, a lineage-specific cytokine, significantly influences megakaryocyte proliferation and maturation, particularly in late developmental stages from committed progenitor cells. It emerges as a potential major physiological regulator, underscoring its crucial role in the intricate orchestration of circulating platelets and emphasizing its importance in megakaryocyte biology and platelet formation. TPO/Thrombopoietin Protein, Human (HEK293) is the recombinant human-derived TPO/Thrombopoietin protein, expressed by HEK293, with tag free.
