一般描述

碳酸氢钠在细胞培养应用中被广泛用作一种生理性缓冲液。 碳酸氢根<->碳酸的pKa是6.4 碳酸氢根<->碳酸盐的pKs是10.3。 碳酸氢钠具有两个pKa,6.4和10.3。 它在体外应用中被广泛用作一种生理性缓冲液。

应用

碳酸氢钠已用于:
  • 作为体外熟化、受精和培养(IVMFC)过程中牛胚胎培养系统的一种成分
  • 作为牛微血管内皮细胞培养过程中Dulbecco′s modified Eagle′s培养基和Ham′s 营养混合物F-121:1混合物中的一种成分
  • 作为从人胚胎干细胞中进行多巴胺神经元分离过程中使用的ITS(胰岛素转铁蛋白和亚硒酸盐)培养基中的一种成分
  • 作为用于人胚肾细胞的细胞培养基中的一种成分
  • 作为用于稀释精液的Beltsville解冻溶液中的一种成分
