2,4,6-三硝基苯磺酸钠(简称 TNBS)在亲和色谱法中用于检定琼脂糖或其他基质上的伯氨基、羧基或溴乙酰基、初级脂肪胺、初级芳香胺、未取代酰肼、硫醇等基团的试剂;使用方便显色灵敏。血清中血管紧张素转换酶(简称 ACE)的比色测定也需要此试剂显色。经我们调查国内无生产单位(进口价格10克为87元,且无货)。为了建立 Sodium 2,4,6-trinitrobenzene sulfonate (TNBS for short) is used in affinity chromatography for the determination of primary, carboxyl or bromoacetyl groups on agarose or other substrates, primary aliphatic amines, primary aromatic amines, Unsubstituted hydrazide, mercaptan and other groups reagents; easy to use color sensitivity. Colorimetric assays of serum angiotensin-converting enzyme (ACE) also require this reagent for color development. After our investigation of domestic production units (import price of 10 grams for 87 yuan, and no goods). In order to build
