An automated procedure for the precolumn derivatization of enantiomeric amino acid mixtures with 1-fluoro-2,4-dinitrophenyl-5-alanine amide and a liquid chromatographic method for the separation of the derivatives with UV detection are reported. The system described allows to perform routine analyses using microbore columns with a sensitivity at the picomol level. Improvements for the use of this reagent in the protocol of a subtractive Edman degradation procedure of peptides to determine the sequence position of amino acid residues with concomitant identification of their chirality are also described.

Abstract

An automated procedure for the precolumn derivatization of enantiomeric amino acid mixtures with 1-fluoro-2,4-dinitrophenyl-5-alanine amide and a liquid chromatographic method for the separation of the derivatives with UV detection are reported. The system described allows to perform routine analyses using microbore columns with a sensitivity at the picomol level. Improvements for the use of this reagent in the protocol of a subtractive Edman degradation procedure of peptides to determine the sequence position of amino acid residues with concomitant identification of their chirality are also described.
