Allele Frequencies for Two STR Loci GATA31E08 and DXS6809 in Chinese Population

Blood samples were collected from unrelated individuals of Chinese Han ethnic group in Chengdu of China. DNAwas extracted using Chelex method (1). PCR amplification conditions can be accessed at http://www.legalmed.org/dna/DXS6809.htm (2). The volume of PCR reaction for each locus was 37.5 µL. The PCR products were analyzed by horizontal non-denaturing polyacrylamide gel electrophoresis with discontinuous buffer system and visualized by sliver staining (2,3). Data were analyzed using POWERSTATS program (4).
