年,来自 Jackson Laboratory 的 C.Ostermeier 等人对脱脂牛奶 / 棉子糖冷冻小鼠精子方法的修改,方法是在 CPA(3%脱脂奶和 18%棉子糖组合)中添加单硫代甘油(MTG),这种方法能让 C57BL/6J 品系受精率提高到 60%。近交系 B6 冷冻的方案得到了质的提升,也能满足冷冻需求。 2010 年,Takeo 和 Nakagata 又改良了冷冻方案,即在原来的组合基础上添加了 L-谷氨酰胺,L-谷氨酰胺是血浆和组织中含量最丰富的游离氨基酸,L-谷氨酰胺具有
性,一般与激素或其它物质起相互协同或加成作用。另一种常见的添加物就是血清替代物,目前已有许多可完全或部分替代传统培养液中血清成分的商业产品,其稳定性较好,但批次间仍有差别,产品的成分也不很确定。2、细胞培养基配制 2.1 干粉培养基原倍液的配制 1)配制过滤除菌的细胞培养基 1)阅读培养基使用说明,确定需要添加何种添加剂(如NaHCO3、L-谷氨酰胺、丙酮酸钠、HEPES等)。 2)根据所需将培养基全部倒入一容器中,用少量注射用水(20℃~30℃)将袋内残留培养基洗下,并入容器。加注射用水至总体
细胞。在进行免疫学 研究、培养ES细胞、昆虫细胞和平滑肌细胞时,推荐使用热灭活血清。 3.L-谷氨酰胺在细胞培养 中重要吗?它在溶液中不稳定吗? L-谷氨酰胺在细胞培养 时是重要的。脱掉氨基后,L-谷氨酰胺可作为培养细胞的能量来源、参与蛋白质的合成和核酸代谢。L-谷氨酰胺在溶液中经过一段时间后会降解,但是确切的降解率一直没有最终确定。L-谷氨酰胺的降解导致氨的形成,而氨对于一些细胞具有毒性。 4.GlutaMAX-I是什么?培养细胞如何利用GlutaMAX
