重組人白血病抑制因子LIF

產(chǎn)品關(guān)鍵詞：

na?ve stem cells 初始干細(xì)胞；neural progenitor cells 神經(jīng)祖細(xì)胞；WH-4-023；CHIR99021；Stemfactor™ Activin A；

產(chǎn)品描述：

Stemfactor™ LIF是一種淋巴因子（lymphoid factor），通過(guò)抑制自發(fā)分化來(lái)促進(jìn)胚胎干細(xì)胞多潛能性的長(zhǎng)期維持。淋巴細(xì)胞抑制因子（Leukemia Inhibitory Factor, LIF）還具有其他功能，比如*能神經(jīng)元分化，骨和脂肪代謝，某些因子依賴(lài)細(xì)胞系的有絲分裂發(fā)生，和促進(jìn)體內(nèi)巨核細(xì)胞的產(chǎn)生。人LIF分子量約20kDa，含202個(gè)氨基酸殘基，對(duì)人和小鼠細(xì)胞都有活性。

Stemgent公司提供支持初始潛能干細(xì)胞應(yīng)用需要的5i/L/A培養(yǎng)基添加劑（5i/L/A media supplment）所有成分，如下：
