所有常见的二甲基氨基偶氮苯硫代乙内酰脲(DABTH)的氨基酸衍生自修改的Edman测序的分离可以通过使用高效液相色谱实现。所有衍生物,包括DABTH-Ile和DABTH-Leu,可以在乙酸钠缓冲液和1%二氯乙烷的乙腈溶液的溶剂混合物中容易地分离。DABTH氨基酸在436 nm处的高吸光度使得在皮摩尔浓度下在相对短的时间(30-40 min)内定量测定这些衍生物成为可能。
The separation of all common dimethylaminoazobenzenethiohydantoin (DABTH) amino acids derived from modified Edman sequencing can be achieved by using high-performance liquid chromatography. All derivatives, including DABTH-Ile and DABTH-Leu, can be readily separated in a solvent mixture of sodium acetate buffer and 1% ethylene dichloride in acetonitrile. The high absorbance of the DABTH amino acids at 436 nm makes possible the quantitative determination of these derivatives at picomole concentrations in a relatively short time (30–40 min).
