[Application of the QIAamp DNA Investigator Kit and Prepfiler Forensic DNA Extraction Kit in genomic DNA extraction from skeletal remains].

The report presents an application of the QIAamp DNA Investigator Kit and PrepFiler Forensic DNA Extraction Kit in genomic DNA extraction from post-mortem highly degraded skeletal remains. The analysis included 25 bone samples collected on autopsy. DNA extraction was performed in accordance with the QIAamp DNA Investigator Kit and PrepFiler Forensic DNA Extraction Kit manufacturer's isolation protocols. Amplification was performed on a Biometra termocycler using the AmpFISTR Identifiler PCR Amplification Kit according to the manufacturer's protocol. Typing of PCR products was carried out on an ABI Prism 377 DNA sequencer. The recommended parameters for GeneScan analysis and Genotyper software were followed. The authors demonstrated that the QIAamp DNA Investigator Kit was more effective, convenient and statistically significantly better method which may be employed in DNA extraction from bone specimens.
