Development of a Forensic Multiplex Amplification STR Kit for 15 Autosomal STR Loci and 10 Y-STR Loci / 法医学杂志

ABSTRACT

OBJECTIVE@#To establish a multiplex STR genotyping method for autosomal STR and Y-STR loci in forensic biological practice.@*METHODS@#Widely used autosomal STR loci and Y-STR loci were selected. A set of PCR primers was designed, and a 5-dye fluorescent labeled STR multiplex PCR reagent kit was developed.@*RESULTS@#A kit was developed which can simultaneously detect 15 autosomal STR loci, 10 Y-STR loci, and an Amelogenin.@*CONCLUSION@#The 15 autosomal STR plus 10 Y-STR kit in combination with capillary electrophoresis method was used to STR genotyping with accurate and reliable results. The new one-step testing kit can potentially be widely used in forensic cases and DNA databank in the future.
