Abstract: Objective To establish a simple,fast and economical technique for multiplex-typing SNPs and to explore its potential forensic application.Methods Five Y-SNP loci(IMS-JST164520,IMS-JST021354,IMS-JST003305,M119 and M134) were selected and the allele specific primers of each locus were designed with the universal reporter primers tailed at their 5′ end.Alleles of these loci were amplified first by al-lele specific primers,then amplified by universal reporter primers tagged by fluorescent dye.Results A fluores-cent-multiplex PCR system of the five Y-SNP loci was established.The typing results showed that two different colors of product peaks denoted two different alleles of a SNP locus,and the fragment sizes of alleles among different SNP loci were different.The haplotype diversity of these five loci was estimated to be 0.865 5 in Wuhan Han population.Conclusion The multiplex-typing SNPs based on the universal re-porter primers is a simple,fast,and economical technique,and may have good application value in forensic medicine.
