表達區(qū)間及表達系統(tǒng)(Source)
Human Thrombopoietin Protein, Tag Free (THN-H5214) is expressed from human 293 cells (HEK293). It contains AA Ser 22 - Gly 353 (Accession # P40225-1).
蛋白結構(Molecular Characterization)
This protein carries no "tag".
The protein has a calculated MW of 35.6 kDa. The protein migrates as 65-80 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
內毒素(Endotoxin)
Less than 0.1 EU per μg by the LAL method.
無菌(Sterility)
Negative
支原體(Mycoplasma)
Negative.
純度(Purity)
>95% as determined by SDS-PAGE.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
血小板生成素(TPO)是一種332個氨基酸的糖蛋白,主要在肝臟中產(chǎn)生,是血小板產(chǎn)生的主要生理調節(jié)因子。TPO結合TPO受體,激活JAK和STAT通路,從而刺激巨核細胞生長和血小板生成。此外,進一步的研究發(fā)現(xiàn),血小板生成素是促進骨髓消融后造血反彈的關鍵細胞因子,其轉錄物由多種細胞來源表達。
