自行配制 DMEM 的方法及说明书这里是一份 GIBCO 的低糖 DMEM 粉剂配制说明(普通高糖的 DMEM 培育基配法是一样的): TO PREPARE 1*LIQUID 1. Measrue out 5 % less distilled water than desired total volume of medium using a mixing container that is as close to the final volume as possible.2. Add powdered medium to 15 to 30℃ (room temperature)water with gentle stirring. (Do not heat water)3。 Rinse out inside of package to remove all traces of powder.4. Add 3.7g of NaHCO3 per liter of medium.5. Dilute to a desired volume with water。 Stir until dissolved. (Do not over—mix)6。 Adjust pH of medium to 0。2—0.3 below desired final working pH* use of IN NaOH or IN HCl is recommended. (Add slowly with stirring) After pH has been adjusted keep container closed until medium is filtered。7 。 Sterilize immediately by membrane filtration. (Positive pressure recommended) *pH unite will usually rise 0。1—0.3upon filtration.另外,在李玲、李雪峰编著的《细胞生物学实验》中配制方法如下:1 制备新奇三蒸水或 Millipore 超纯水。2 称取所需量的干粉培育基,加入约终体积一半的三蒸水中;若配制一个包装的培育液,在将整个包装的干粉倒入三蒸水后,需用水洗包装袋内面 2 次,倒入培育液中,以保证所有干粉都溶解成培育液。磁力搅拌或人工搅拌使之完全溶解。3 根据包装袋上的要求补加所需量的碳酸氢钠 ;根据实验需要,添 HEPES(5—20mmol/L)、谷氨酰胺和其他特别物质.4 加水定容到终体积。5 必要时用 1 mol/L 盐酸和 1 mol/L 氢氧化钠调节 pH.6 用无菌 0。22um 滤膜过滤除菌,分装于无菌血清瓶中,4℃冰箱保存。配制好的培育液用前加入 100U/mL 青霉素和 100U/mL 链霉素,并根据需要加入血清(5%—20%)。
