Article Title: Onset of channeling during DNA electrophoresis in a sparse ordered post array
Figure Lengend Snippet: (a) Mobility of pUC19 as a function of the electric field. Each data point represents the average of three to five data points. (b) Images of pUC19 and λ-DNA under an electric field of 20 V/cm. The images were taken at the same location in the post array (10 mm downstream) with an offset of Δ t =25 s (enhanced online). (c) Representative electropherograms obtained 15 mm downstream under electric fields of 20, 40, 60, 80, and 100 V/cm. Each electropherogram corresponds to an individual experiment. The fluorescence intensity for each electropherogram has been rescaled to a maximum intensity of unity.
Article Snippet: Our experiments used linear λ-DNA (48 500 base pairs, New England Biolabs) and the circular pUC19 plasmid DNA (2686 base pairs, New England Biolabs).
