內(nèi)毒素(Endotoxin)
Less than 0.01 EU per μg by the LAL method.
宿主蛋白殘留(Host Cell Protein)
<0.5 ng/μg of protein tested by ELISA.
宿主核酸殘留(Host Cell DNA)
<0.02 ng/μg of protein tested by qPCR.
無菌(Sterility)
Negative
支原體(Mycoplasma)
Negative.

背景(Background)
FMS樣酪氨酸激酶3配體(Flt-3配體)也稱為FL、Flt3L和FLT3LG,是一種促進多種造血細胞系分化的α-螺旋細胞因子。FLT3LG被T細胞、骨髓和胸腺成纖維細胞表達為非共價性二聚體。每條36 kDa的鏈攜帶大約12 kDa的N和O連接的碳水化合物。FLT3LG在結(jié)構(gòu)上與干細胞因子(SCF)和集落刺激因子1(CSF-1)同源。FLT3LG作為一種生長因子,通過激活造血祖細胞來增加免疫細胞的數(shù)量。它還在體內(nèi)誘導造血祖細胞和干細胞的動員,這可能有助于系統(tǒng)殺死癌癥細胞。FLT3LG誘導單核細胞和未成熟樹突狀細胞的擴增以及早期B細胞譜系分化。FLT3LG與IL2、IL6、IL7和IL15合作誘導NK細胞發(fā)育,與IL3、IL7、IL11合作誘導終末B細胞成熟。動物研究還表明,FLT3LG可以減輕實驗誘導的過敏性炎癥的嚴重程度。FLT3LG對穩(wěn)態(tài)pDC和cDC的發(fā)育至關(guān)重要。FLT3L的缺乏導致DC水平低。
