| Figure 1. Data quality analysis based on PHRED q>20 scores. Average read length of both single-stranded and double-stranded DNA samples were analyzed on the ABI Prism® 3700 under standard run conditions 3 hours at 1,000V, 50 °C. Samples were prepared using BigDye™ terminators with SigmaSpin™ post-reaction clean up. |
