文献和实验学功能活性,还有利于维持细胞因子的稳定性,延长其半衰期。 图4 不同宿主表达IL-4在细胞培养基中的稳定性比较(37C, 5 days) 例如白介素4,如上图所示:人源细胞表达生产的IL-4由于具有正确完整糖基化修饰,SDS-PAGE的表观分子量为20 kDa左右,而E.Coli来源的IL-4缺乏糖基化,因而分子量仅为14 kDa。由于具有正确的糖基化,因此,将等量两种不同宿主来源的细胞因子加入到细胞培养基中在37度下培养5天后,细菌来源的白介素4活性显著降低
69、CD38 等活化指标,及 IFN-γ、IL-4、IL17A 等细胞因子,则需要设置同型对照,实现阴阳性细胞群的良好区分。 CD4 CD25 (2)在某些特殊情况下,如单核细胞被 PE/Cyanine 7、APC/Cyanine 7 等串联染料标记的抗体染色时,使用同型对照抗体是十分有必要的。单核细胞一般倾向于与 Cyanine7 等染料非特异性结合,使用同型对照抗体有助于获得理想结果。 (3)不清楚抗原表达情况的时候,一定要使用同型对照来界定阴性细胞群。 (4)胞内染色时
