ISOELECTRIC POINT MARKERS

摘要

The present invention relates to the field of isoelectric focussing or 2D electrophoresis, in particular isoelectric point markers with fluorescence detection. The marker comprises an oligopeptide covalently labelled with a fluorescent dye and is characterised in that said dye has a net charge that will maintain the overall net charge of the oligopeptide upon being bound to said oligopeptide. The invention also relates to an electrophoretic method for analysis of proteins using these markers.
