摘要

Amino acids and peptides, from both standard solutions and biological samples, were successfully reacted with 34 4-carboxybenroyi)-2-quinoiinecarboxaidehyde, at low concentration, to form highly fluorescent isoindole derivatives. The formed mixtures are effectively separated by high-performance capillary electrophoresis and their constituents detected by their laser-induced fluorescence signals. The minimum detectable quantities ...
