Next-generation DNA sequencing workflows require an accurate quantification of the DNA molecules to be sequenced for optimal performance of the instrument. Here, we demonstrate the use of qPCR for quantification of DNA libraries used in next-generation sequencing. We find that the quantification data generated with the Bioanalyzer and qPCR are comparable for high quality library preparations. We also show that qPCR quantification may allow improvements to current NGS workflows, including reducing the amount of library DNA required, increasing the accuracy in quantifying amplifiable DNA, and avoiding amplification bias by reducing or eliminating the need to amplify DNA before sequencing.
