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[1]
  • 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[2]
  • 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[3]
  • 作为用于人胚肾细胞的细胞培养基中的一种成分[4]
  • 作为用于稀释精液的Beltsville解冻溶液中的一种成分[5]

    Screening for Estrogen Active Nonylphenols in Water by Planar Solid Phase Extraction – Planar Yeast Estrogen Screen

    Nonylphenols (NP) are ubiquitous substances that have been detected in highly diverse foodstuff. As breakdown products of nonylphenol ethoxylates, NP could end up in the aquatic environment. This article presents a rapid method for NP detection in surface water by planar solid phase extraction – planar yeast estrogen screen (pSPE-pYES).
