Abstract: Objective To test the technical parameters of GlobalFiler?誖PCR Amplification Kit for its application to forensic application value and to investigate the genetic polymorphisms. Methods The validation was conducted in sensitivity, mixed samples, species specificity, adaptability, survivability, consistency, peak height balance and stability. The amplification and detection of the genomic DNA from 373 unrelated individuals from Beijing Han nationality were extracted by automation workstation. Results GlobalFiler?誖PCR Amplification Kit was adaptive to some mixed, degraded and inhibited samples. The power of sensitivity and adaptability and peak height balance showed well. The distributions of genotype frequencies for 21 STR loci in the population were all in accordance with Hardy-Weinberg equilibrium （P＞0.05）. The PIC value of the 21 STR loci was among 0.536 to 0.940; the H value was among 0.558 to 0.933; the DP value was among 0.783 to 0.992; the PE value was among 0.243 to 0.874. Conclusion GlobalFiler?誖PCR Amplification Kit is suitable for criminal cases and DNA database in forensic practice. And 21 STR loci in Beijing Han nationality have high polymorphism, which have application value in forensic practice and population genetics.
