Notes: DNA templates are often amplified by PCR during library generation prior to next-generation sequencing, but amplification can introduce biases and duplications that are not easily corrected. In this paper, the authors developed a simple method to count the number of input template molecules to reduce these PCR-related problems: The ligation of a degenerate base region to all fragments during library creation. To evaluate their approach to correct for biases and duplications, the authors created a library using Human Genomic DNA, amplified the library by inverse PCR using the GoTaq® Hot Start Polymerase and 1X Colorless GoTaq® Flexi Buffer, sequenced the resulting DNA fragments and assessed the quality of the next-generation sequencing data.
