Conventional genomic DNA (gDNA) extraction methods can take hours to complete, may require fume hoods and represent the most time-consuming step in many gDNA-based molecular assays. We systematically optimized a bead bashing-based (BBB) approach for rapid gDNA extraction without the need for a fume hood. Human tissue specimens (n = 34) subjected to the 12-min BBB method yielded 0.40 ± 0.17 (mean ± SD) μg of gDNA per milligram of tissue, sufficient for many downstream applications, and 3- and 6-min extensions resulted in an additional 0.43 ± 0.23 μg and 0.48 ± 0.43 μg per milligram of tissue, respectively. The BBB method provides a simple and rapid method for gDNA extraction from mammalian tissue that is applicable to time-sensitive clinical applications.
