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.

Accurate, rapid, and multiplex SNP analysis holds significant clinical value. However, the inevitable nucleic acid extraction, involving centrifugation, heating, and magnetic separation, is often time-consuming. In this study, direct blood PCR was combined with dual-labelled probe-mediated melting curves to identify SNPs corresponding to MTHFR (C677T, rs#1801133 and A1298C, rs#1801131) and MTRR (A66G, rs#1801394) in a single tube.

Here, we present a protocol for iterative enrichment of integrated single guide RNA (sgRNA) via derivative CRISPR-Cas9 from genomic DNA (gDNA) of phenotypically sorted fixed cells. We describe steps for high-scale lentiviral production, genome-wide screening, extracting gDNA from fixed cells, cloning of integrated sgRNAs, and high-scale transformation. This protocol introduces three key advantages: (1) applicability to fixed cells, (2) bypassing epigenetic drift, and (3) pause points lowering the contamination risk.
