| Abstract: | Objective To investigate the application of the DNA IQTM SYSTEM in extraction of DNA from nail samples.Methods The genomic DNA from 15 difficult nail samples was extracted by the DNA IQTM SYSTEM and the PCR was performed using the identifiler○ RPlus kit in the GeneAmp PCR system 9700.The PCR products were separated by capillary electrophoresis in ABI PRISM 3130xL genetic analyzer.Results the STR profiles from the 15 samples were successfully obtained.Conclusion The DNA IQTM SYSTEM is a fast and efficient system for the extraction of the DNA from difficult nail samples. |
