Application of forensic genetics in archaeology enables retrieving new types of information and helps in data interpretation. The number of successfully typed autosomal and Y-STR loci from ancient specimens in this study is one of the largest published so far for aged samples.
The aim of this preliminary study was to compare the quantity and quality of DNA extracted from a variety of forensic samples using a MagCore HF 16 Plus automated nucleic acid extractor (RBC Bioscience, Taiwan) and MagCore ® Genomic DNA Forensic Kit and a manual procedure employing the ZR Genomic DNA-Tissue MicroPrep (ZymoResearch, USA) kit. The whole purification process using a MagCore HF 16 Plus automated nucleic acid extractor is fully automated and requires no sample pretreatment. The scope of forensic samples tested comprised standard reference samples (mouth swabs taken on rayon and nylon swabs (Copan, Italy), blood, saliva and sperm on storage cards, cigarette ends, hair samples, chewing gum, and epithelial cells on lifting tapes).
There are several manufacturers that offer forensic DNA-grade products that comply with ISO 18385:2016. We have compared the particular procedures and protocols and suggest a way forward for compliance testing of forensic DNA-grade products.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
