Animal-Free TPO/Thrombopoietin 蛋白, Human (His)

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. Animal-Free TPO/Thrombopoietin Protein, Human (His) is the recombinant human-derived animal-FreeTPO/Thrombopoietin protein, expressed by E. coli , with N-His labeled tag. The total length of Animal-Free TPO/Thrombopoietin Protein, Human (His) is 174 a.a., with molecular weight of ~19.6 kDa.

血小板生成素 (TPO) 是一种谱系特异性细胞因子，对巨核细胞的增殖和成熟发挥关键影响，特别是在其从定型祖细胞发育的后期阶段。值得注意的是，TPO 在循环血小板的复杂编排中成为潜在的主要生理调节剂，强调了其在巨核细胞生物学和血小板形成中的关键作用。

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

无菌粉末.

Lyophilized from a solution containing 1X PBS, pH 7.4, trehalose.

< 0.01 EU per 1 μg of the protein by the 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. 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.
