TPO/Thrombopoietin Protein, Mouse (HEK293)

Customer Review

Based on 1 Customer Validation

TPO/Thrombopoietin Protein, a lineage-specific cytokine, crucially regulates megakaryocyte proliferation and maturation, acting in the late stages of development from committed progenitor cells. Recognized as a major physiological regulator, TPO significantly influences circulating platelets, emphasizing its importance in the intricate process of platelet formation. TPO/Thrombopoietin Protein, Mouse (HEK293) is the recombinant mouse-derived TPO/Thrombopoietin protein, expressed by HEK293 , with tag free.

Biological Activity

Description

TPO/Thrombopoietin Protein, a lineage-specific cytokine, crucially regulates megakaryocyte proliferation and maturation, acting in the late stages of development from committed progenitor cells. Recognized as a major physiological regulator, TPO significantly influences circulating platelets, emphasizing its importance in the intricate process of platelet formation. TPO/Thrombopoietin Protein, Mouse (HEK293) is the recombinant mouse-derived TPO/Thrombopoietin protein, expressed by HEK293 , with tag free.

Background

Thrombopoietin (TPO), a lineage-specific cytokine, plays a crucial role in regulating the proliferation and maturation of megakaryocytes, acting at a late stage of their development from committed progenitor cells. Functioning as a key factor in megakaryopoiesis, TPO is recognized as a major physiological regulator of circulating platelets. Its influence on the later stages of megakaryocyte development underscores its significance in the intricate process of platelet formation.

Verified Bioactivity

Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. The ED50 for this effect is 0.4-2.4 ng/mL.
