产品介绍
Dulbecco的改良Eagle培养基—DMEM(Dulbecco's Modified Eagle Medium)是一种广泛使用的基础培养基,适用于多种哺乳动物细胞培养,包括原代成纤维细胞,神经元,神经胶质细胞,HUVEC和平滑肌细胞,以及HeLa,293,Cos-7和PC-12等细胞系。DMEM是在MEM培养基的基础上研制的,与MEM培养基相比,氨基酸的含量增加了2倍, 维生素增加了4倍,同时还增加了非必需氨基酸、微量铁离子以及丙酮酸钠。 DMEM培养基最初设计为葡萄糖含量1000mg/L的低糖型,后来又发展出葡萄糖含量为4500mg/L的高糖型,现已广泛应用于各种细胞的培养。DMEM低糖培养基更适合代谢作用较慢、依赖性贴壁细胞的培养。 L-丙氨酰-L-谷氨酰胺是一种高级细胞培养添加剂,可直接替代L-谷氨酰胺。L-谷氨酰胺是细胞培养液体环境中所必需的一种营养成分,但其在水溶液中不稳定,易降解产生对细胞有害的氨;而L-丙氨酰-L-谷氨酰胺在水溶液中十分稳定,不会自发降解,其被细胞利用的机制为:细胞在培养时会向培养液中释放一种肽酶,将L-丙氨酰-L-谷氨酰胺逐渐水解成L-丙氨酸和L-谷氨酰胺,这种将低浓度水平的L-谷氨酰胺逐渐释放到培养液中的过程类似于流加培养策略,可以提高L-谷氨酰胺的利用率,且不会产生多余的氨,更利于细胞的生长。L-丙氨酰-L-谷氨酰胺可以代替等摩尔的L-谷氨酰胺,适用于所有的细胞,几乎无需适应,并且可以延长细胞的培养时间,减少传代次数,细胞活性降低得更慢。L-丙氨酰-L 谷氨酰胺的添加可能导致延滞期略微延长,其原因是肽酶的释放和二肽的消化需要一定的 时间,不影响后续培养。 本产品含有:D-葡萄糖(1000mg/L)、酚红、丙酮酸钠、L-丙氨酰-L-谷氨酰胺。 不含有:L-谷氨酰胺、HEPES。
