STR data for the AmpFlSTR profiler plus from western China.

B. W. Ying; Y. G. Wei; X. M. Sun; Y. P. Hou

Blood samples were collected from unrelated individuals ofChinese Han ethnic group in Chengdu of China. DNA was ex-tracted using Chelex method (1). 0.5–2ng target DNA followedthe protocols described in the AmpFlSTR Cofiler user’s manual(PE Applied Biosystems), the exception was that the PCR vol-umewas25µL.ThesampleswereamplifiedusingGeneAmpPCRSystem 9700 (Applied Biosystems, Foster City, CA). DNA typ-ing was carried out on the ABI 3100 Genetic Analyzer (AppliedBiosystems). The amplified products were detected with the ABIPRISM 3100 Genetic Analyzer using the separation medium Per-formance Optimized Polymer (POP) 4

Blood samples were collected from 100 unrelated healthy males of the Chinese Han ethnic group in Chengdu of China. DNA was extracted using the Chelex method (1). The allelic variation at the two Y-STR loci named as DYS632 and DYS634 were analyzed by PCR amplification system. PCR amplification conditions can be accessed at: http://www.legalmed.org/dna/DYS632.htm. 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 silver staining (2). Alleles were designated according to the recommendation of the International Society of Forensic Genetics (3). The gene diversity, the haplotype diversity, and the standard errors of diversity were calculated in accordance with Hou’s method (4). The complete data can be accessed at: http://www.legalmed. org/dna/DYS632.htm.

X. H. Song; P. Bai; L. Tian; Libing Yun; W. A. Yuan; B. W. Ying; Jingquan Zhang; Youping Li; Jiagang Wu; Y. P. Hou

Blood samples were collected from unrelated healthy individuals of Chinese Han ethnic group in Chengdu of Sichuan, China after informed consent. Genomic DNA samples were extracted using Chelex-100 method (1). PCR amplification conditions can be accessed at http://www.legalmed.org/dna/D19S591.htm., http:// www. legalmed.org/dna/D5S1462.htm. and http://www.legalmed. org/ dna/D3S2432.htm. The volume of PCR reaction for each locus was 37.5μL. The PCR products were analyzed by horizontal nondenaturing polyacrylamide gel electrophoresis with discontinuous buffer system and visualized by silver staining (2). Data of population genetics and forensic science of the locus D19S591, D5S1462, D3S2432 was analyzed using POWERSTATS program (3). The

B. W. Ying; Jianying Tang; Y. Z. Gao; Y. P. Hou; Youping Li; Jing Wu; Jingquan Zhang; J. Yan

Blood samples were collected from unrelated individuals of Chinese Han ethnic group in Chengdu of China. DNA was extracted using Chelex method (1). Reaction condition of PCR amplification can be accessed at http://www.legalmed.org/ dna/D11S1977.htm. 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 silver staining (2,3). Data of population genetics and forensic science were analyzed using POWERSTATS program (4). The genotype distribution was analyzed for Hardy-Weinberg equilibrium according to Hous method (5) and no deviation from Hardy-Weinberg equilibrium was observed.
