Removal of dye-labeled dideoxy terminators from dna sequencing reactions

摘要

This invention provides methods for removing unincorporated fluorescent dye-labeled molecules from a mixture that includes fluorescently-labeled polynucleotides and the unincorporated fluorescent dye-labeled molecules. The methods involve adsorbing the unincorporated fluorescent dye-labeled molecules into a plurality of particles that are made up of one or more porous hydrophobic materials that are encapsulated in a hydrophilic matrix.
