描述
Sodium Bicarbonate is buffer commonly used for maintaining the pH of cell culture medium in the presence of 4–10% carbon dioxide. In addition to buffering, sodium bicarbonate provides some nutritional benefit, while rarely displaying any cell toxicity. Formulated as 75 g per liter of water, Gibco® Sodium Bicarbonate, 7.5% Solution is perfect for supplementing dry powder medium during reconstitution. The final Sodium Bicarbonate concentration used in the medium depends on the media formulation and the carbon dioxide concentration used in the incubator.Product Use

文献和实验与所有的化学平衡一样,当溶液的浓度、温度等条件改变时,弱酸、弱碱的解离平衡会发生移动。就浓度的改变来说,除用稀释的方法外,还可在弱酸、弱碱溶液中加入具有相同离子的强电解质以改变某一离子的浓度,从而引起弱酸或弱碱解离平衡的移动。例如,往 HAc 溶液中加入 NaAc ,由于 Ac - 离子浓度增大,使平衡向生成 HAc 的一方移动,结果就降低了 HAc 的解离度。又如,往 NH 3 水溶液中加入 NH 4 Cl ,由于 弱酸溶液中加入该酸的共轭
潭深水静 请教各位园友: 新买的 anisomycin用什么溶液溶解保存。 谢谢! 潭深水静 主要用来刺激p-38,有用生理盐水稀释到终浓度的 但不知道用什么来溶解配母液 yhwangcams 根据sigma的说明,可以用多种溶液配制母液: solubility ethanol: 12 mg/mL solubility H2O: 2 mg/mL
溶液是由两种或多种组分组成的均匀体系。所有溶液都是由溶质和溶剂组成,溶剂是一种介质,在其中均匀地分布着溶质的分子或离子。 溶质和溶剂只有相对的意义。通常将溶解时状态不变的组分称作溶剂,而状态改变的称溶质。如,糖溶于水时,糖是溶质,水是溶剂。若组成溶液的两种组分在溶解前后的状态皆相同,则将含量较多的组分称为溶剂。如在 100 mL 水中加入 10 mL 的酒精组成溶液,水是溶剂。若体积掉换一下,则酒精为溶剂。有时两种组分的量差不多,此时可将任一种组分看作是溶剂
