Quality control of fragmented DNA. (A) Bioanalyzer results from three DNA samples fragmented either in glass tubes with a Covaris DNA shearing device (Duty cycle 10%, Intensity 4.5, Cycles per burst 200, Time 120 s), or in PCR strips with a Bandelin sonicator (2 times 4 min). (B) 1.5% agarose gel loaded with 22 samples fragmented by Bandelin sonication. The size distribution is very narrow (major peak between 100–300 bp) and has an acceptable reproducibility.
