On-column digestion of protein for peptide mapping by capillary zone electrophoresis with laser-induced native fluorescence detection
Abstract
We have developed a novel technique to separate and detect peptide fragments which are digested on the same column. In this procedure, pepsin is used to digest low femtomole amounts of [beta]-lactoglobulin on the column. Then, CZE and LINF are applied to separate and detect the peptide fragments. The advantages of this method are its simplicity, high sensitivity, high selectivity, efficient operation, and high speed. 38 refs., 6 figs., 2 tabs.
