Abstract excerpt
Diblock copolymers composed of allele-specific oligodeoxyribonucleotide (ODN) and poly(ethylene glycol) (PEG) are used as an affinity probe of free-solution capillary electrophoresis to quantitatively detect single-base substitutions in genetic samples. During electrophoresis, the probe binds strongly to a wild-type single-stranded DNA analyte (WT) through hybridization, while it binds weakly to its...
