  • Removal of dye-labeled dideoxy terminators from DNA sequencing reactions
    Patent number: 6818760
    Abstract: This invention provides methods for removing unincorporated dye-labeled molecules from a mixture that includes dye-labeled polynucleotides or other polymers and the unincorporated dye-labeled molecules. The methods involve adsorbing the unincorporated 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.
    Type: Grant
    Filed: October 6, 2000
