Permanganate-assisted removal of PCR inhibitors during the DNA Chelex extraction from stained denim samples.

In this study, it was demonstrated that the DNA Chelex extraction combined with the permanganate assisted-oxidation is highly efficient in removing the PCR inhibitors often found in clothing materials, such as phthalocyanine. The extraction assays were conducted in saliva, blood and epithelial cells samples mixed with three oxidation-resistant dye copper(II) α-phthalocyanine, copper(II) β-phthalocyanine and tetrasulfonated copper(II) β-phthalocyanine. After DNA amplification, all samples were able to provide full DNA profiles.

Population data for Y-chromosome haplotypes defined by 17 STRs in South-East Romania.

Haplotypes and allele frequencies for 17 STR loci included in AmpFlSTR YFiler kit (DYS456, DYS389I, DYS390, DYS389II, DYS458, DYS19, DYS385a/b, DYS393, DYS391, DYS439, DYS635, DYS392, Y GATAH4, DYS437, DYS438 and DYS448) were determined in a sample of 122 unrelated males living in the South-East Romania. Genetic distances had been calculated and dendrograms had been generated for South-East Romanian population and other eighteen surrounding populations.
