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).
