Studies from N. Hu et al Provide New Data on DNA Research

August 8, 2014

By a News Reporter-Staff News Editor at Health & Medicine Week -- Data detailed on DNA Research have been presented. According to news reporting from Beijing, People's Republic of China, by NewsRx journalists, research stated, "The analysis of complex DNA mixtures is challenging for forensic DNA testing. Accurate and sensitive methods for profiling these samples are urgently required."

The news correspondents obtained a quote from the research, "In this study, we developed 11 groups of mixed male DNA samples (n=297) with scientific validation of D-value [>95% of D-values 0.6 with the APH >= 1,250. The variation of Hb distribution in the different STR loci suggested the different forensic efficiencies of these loci. Allelic drop-out (ADO) correlated with the APH and mixed gradient. All ADOs had an APH of

According to the news reporters, the research concluded: "These results strongly suggest that calibration parameters should be introduced to correct the deviation in the APH at each STR locus during the analysis of mixed DNA samples."
