Comparison between classic agarose gel electrophoresis and chip technology for resolution and accuracy. The same samples were analyzed by electrophoresis onto 3% agarose gel (a) and Bioanalyzer 2100 (b). The molecular weight of the upper band in the S1 line of the agarose gel is not unambiguously assignable. b Gel-like image and electropherograms of samples S1 and S2 obtained by Bioanalyzer 2100 analysis. The exact length of the longer fragment is easily determined (Mk molecular weight marker)
