TPO/Thrombopoietin Protein, Human (HEK293)

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.

Thrombopoietin (TPO), a lineage-specific cytokine, exerts a pivotal influence on the proliferation and maturation of megakaryocytes, particularly at the late stages of their development from committed progenitor cells. Notably, TPO emerges as a potential major physiological regulator in the intricate orchestration of circulating platelets, underscoring its crucial role in megakaryocyte biology and platelet formation.

Approximately 70-80 kDa, based on SDS-PAGE under reducing conditions, due to the glycosylation.

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from 0.22 μm filtered solution of 20 mM NaAc-HAc, pH5.0 with 11% trehalose as protectant.

<0.01 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
