酚红(Phenol Red)可增加活细胞荧光成像时的背景,并对细胞具有光毒性 Maintaining Live Cells on the Microscope Stage Although the indicator dye is essential for routine cell culture, due to the high visible light absorption extinction coefficient, its use should be avoided in live-cell fluorescence imaging experiments in order to reduce the level of background noise and to prevent phototoxicity. Recognizing this fact, manufacturers provide most of the common media formulations in sterilized liquid or powder form without Phenol red 胰岛素(Insulin)则会干扰对由胚胎干细胞分化而成的胰岛素分泌细胞的检测
PeproGrow-hESC胚胎干细胞培养基是化学成分明确的完全培养基,不含血清和酚红,专门用于人类胚胎干细胞(hESCs)和诱导多能干细胞(hiPSCs)的无饲养层维持培养和扩增(需以BD MatrigelTM作为表面包被基质)。该培养基可保持hESCs 和hiPSCs的未分化、多能状态(SSEA4+/Oct4+),流式细胞术分析显示自发分化的细胞比例低于15%。该培养基的独特配方中含有FGF2(碱性成纤维细胞生长因子)等生长因子,但不含市场上大多数其他品牌胚胎干细胞培养基中存在的胰岛素。PeproGrow-hESC胚胎干细胞培养基由美国PeproTech公司和美国Rutgers(罗格斯)大学干细胞培训中心合作设计与研发,包含一瓶100ml或500ml基础培养基和一管单独的重组生长因子冻干粉。
