Single nucleotide resolution of components of poly(U) (Sigma) by capillary electrophoresis in Pluronic F127. The size range of distinguishable components is estimated as approximately 5–60 nt based on comparison with the mobilities of dTn samples of known lengths. Electrophoresis was performed in 25% Pluronic in TBE buffer at 25°C with an applied voltage of 18 kV (500 V/cm).
