Abstract

A new method based on DNA melting has been developed for the rapid analysis of STRs in the human genome. The system is based on homogeneous PCR followed by fluorescence melting analysis and utilises a HyBeacon® probe combined with a PCR primer-blocker oligonucleotide. The use of blockers of different length permits identification of the full range of common D16S539 repeats enabling detection of 99.8% of known alleles. The interrogation of STRs can be carried out on standard genetic analysis platforms and could be applied to other loci to form the basis of a bespoke high-throughput system for use in forensic analysis, particularly as fluorescent genetic analysis platforms are now available for high-resolution melting. This methodology may be suitable for rapid forensic DNA analysis at the point-of-arrest or in a custody suite where it is important to identify an individual from a small group of suspects/detainees.
