We assessed a cellulose based resin in comparison with DNA IQ™ resin and bench-marked against a modified organic method for processing contemporary and old bones. Additionally, preprocessing buffers – Bone Incubation Buffer and Demineralization Buffer (Lorielle et al., 2007 ) were compared for DNA extraction efficiency using the DNA IQ™ resin chemistry and further compared to a competitor workflow. The results indicate that preprocessing of bone samples using demineralization buffer, followed by DNA purification using the DNA IQ™ chemistry offers an easy, automatable workflow for obtaining DNA that is pure and free of inhibitors. The extracted DNA was compatible with downstream applications such as PowerQuant® System and PowerPlex® Systems, thus enabling accurate human DNA quantification and STR profile generation.
