Application of victims' fingernails in Forensic DNA analysis.
Artículo en Inglés | IMSEAR | ID: sea-134627
ABSTRACT
DNA extracted from the victims’ fingernails may assist in the identification of the aggressor. Fingernails were collected from 8 victims, and were subjected to DNA extraction using the Kit « Tissue and Hair Extraction Kit (Promega) ». All samples were typed for 15 autosomal short tandem repeats and for amelogenin using the Kit « Powerplex TM16 system (Promega) » and the ABI Prism 310 DNA sequencer. The profiles obtained were compared with those achieved by similar typing of victims’ and suspects’ blood. In two Forensic investigations, mixed genotypes were detected in DNA extracted from the nails Alleles originating from the victim were coamplified with other alleles that matched the suspect’s genotypic profile. This indicated that victims’ fingernails contained biological material (blood, epithelial cells) originating from the suspect. Our results confirmed the usefulness of the nails as a specimen for forensic identification of the aggressor.
