Fluorescent high-density labeling of DNA: error-free substitution for a normal nucleotide.

Abstract excerpt

The enzymatic incorporation of deoxyribonucleoside triphosphates by a thermostable, 3'-->5' exonuclease deficient mutant of the Tgo DNA polymerase was studied for PCR-based high-density labeling of 217-bp "natural" DNA in which fluorescent-dUTP was substituted completely for the normal dTTP. The amplified DNA carried two different sorts of tethered dye molecules. The rhodamine-green was used for internal tagging...
