  1. The samples were divided into three test groups: U-SQ: unstained slides were scraped using a razor blade and gDNA was isolated by the Qiagen FFPE column; H-PQ: Pinpoint solution was applied to H&E stained slides, followed by extraction using the Qiagen column or Zymo column (H-PZ). See Methods for details. *Statistically significant lower yield (p = .0005).
