  • Title: Migration behavior of isoluminol isothiocyanate-labeled alpha-amino acids in capillary electrophoresis with an absorption/chemiluminescence dual detection system.

    Abstract:
    In our previous study, we developed capillary electrophoresis with an ultraviolet absorption/chemiluminescence dual detection system. Here, to demonstrate one of the possible applications of the capable system as well as confirm the advantage, migration behavior of isoluminol isothiocyanate-labeled alpha-amino acids was examined in the capillary electrophoresis with a dual detection system. The labeled samples were first analyzed by absorption detection with an on-capillary, followed by chemiluminescence detection with an end-capillary. The system easily, rapidly, and simultaneously produced useful information concerning chemiluminescence quenching and amino group-labeling due to the presence of both absorption and chemiluminescence detections.
