Abstract
Reagents and methods for preparing samples containing both biomolecule analytes and macrobiomolecules for capillary electrophoresis separation are provided. The reagents comprise a branched polymer. When mixed with a sample containing both biomolecule analytes and macrobiomolecules, particularly DNA templates, the branched polymer of the reagent can suppress the entrance of the macrobiomolecules into a capillary electrophoresis tube during electrokinetic injection of the sample into the capillary electrophoresis tube.
