Background: A simple and effective modified ethanol precipitation-based protocol was described for the extraction of genomic DNA from ancient human bones. The qualitative and quantitative evaluation of genomic DNA was done based on DNA purity (260/280) and the PCR method. Method and Materials: In this study, a total of 50 embalmed ancient bones, including 20 long and 30 hip bone samples, were taken for genomic DNA extraction. The efficiency of the genomic DNA extraction was demonstrated on >50-year-old ancient human HIP and long bone samples. In vitro quantitative and qualitative analysis of extracted genomic DNA was performed by 0.8% agarose gel electrophoresis and PCR amplification. To assess the quality of extracted genomic DNA, a mitochondrial-specific ATPase6 gene primer was used to obtain sequence information of 675 bp. Result: Our data show that a concentration of genomic DNA between 1.6 and 2.0 at 260/280 resulted in successful PCR amplification. Our results demonstrated that the extraction of DNA from ancient bone samples with a manual approach will increase the amplification efficiency of the polymerase chain reaction (PCR). Conclusion: In the present study, a simple, time-saving, and cost-effective protocol is described for the extraction of genomic DNA from ancient human bones. Further, we believe the extraction of genomic DNA from ancient bone samples with this approach will increase the success rate of PCR amplification.
