In this experiment, the QIAGEN GeneRead DNAseq V2 Human Comprehensive Cancer Panel (cat. no. 181901) was used to generate PCR products [A] from a reference DNA sample. [B] A library was prepared from 25 ng of purified PCR product using the QIAseq 1-Step Amplicon Library Kit. Only 4 amplification cycles after library preparation were applied. Note that libraries display an appropriate size-shift and are free from adapter-adapter products (~125 bp).
