根据人指纹的ABO血型鉴定进行个人识别是近年来法医物证学中的一项重要课题.指纹是法庭科学鉴定中最常见的物证之一,由于指纹中含有微量的ABH血型物质,运用适当的方法检测,可进行血型判定达到个人识别.近年来,国内外法医物证学工作者做了大量的研究工作,积累了较为丰富的资料.特别是随着刑事犯罪手段日益复杂化、高智商化的情况下,有关指纹ABO血型鉴定的研究也取得了较快的进展.现综述如下: 相似文献

法医物证是指与人体有关的生物物证,包括案发现场存留的血液。精液、阴道分泌液、乳液、唾液、鼻涕、尿液、羊水及瘢痕、毛发、指甲、骨骼和牙齿以及人体各种组织和碎块等。通过对上述检材进行生物学检测,可起到个体识别或同一认定的作用,法医物证DNA结论的采纳,是法庭科学的难点问题, 相似文献

法医物证学DNA检验现状及展望 总被引:1,自引:1,他引:0
个体识别和亲子鉴定是法医物证学检验的主要内容,用于法医物证学的检验方法一般有两类:法医血清学检验和法医分子生物学检验。前者包括血清学、免疫学和生物化学的理论和方法,可用于红细胞血型(ABO、MN、Rh等)、红细胞酶型(PGMI、GLOI、DNaseI等)、血清蛋白型(HP、Gc、Pi等)和白细胞抗原(HLA)的检测。这些遗传学标志为蛋白质(包括糖蛋白)或多肽,容易失活而导致检材得不到理想的检验结果。此外,这些遗传标志均为基因编码的产物,多态信息含量(PIC)有限,不能反映DNA编码区的多态性,且这些遗传标志存在生理性、… 相似文献

All loci, except for D8S1179 and D5S818, are in Hardy-Weinberg equilibrium. 相似文献

Allele frequencies, together with some parameters of forensic interest, for 17 STRs included in the AmpF/STR Identifiler (CSF1PO, D2S1338, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D19S433, D21S11, FGA, TH01, TPO and VWA) and Powerplex 16 System (CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, Penta D, Penta E, TH01, TPO and VWA) were estimated from a sample of 135-144 unrelated individuals from Mozambique. No deviations from Hardy-Weinberg equilibrium were observed with the exception of the FGA locus (using the Bonferroni correction for the number of loci analysed, the departure observed at this locus was not significant). Comparative analyses between our population data and other African databases, namely Promega's African-Americans, AB Applied Biosystems African-Americans and two other population samples from Mozambique and Guiné Bissau, are presented and discussed. Genotype inconsistencies between both commercial kits (for D16S539 and D8S1179) and other genotypic variations (three-banded allele patterns for TPO) are also reported. 相似文献

The molecular origin of DNA mutations and the mutation rates were analyzed at 14 short tandem repeat (STR) loci with samples from trio cases derived from 10 different German population samples. STR loci comprised of D2S1360, D3S1744, D4S2366, D5S2500, D6S474, D7S1517, D8S1132, D10S2325, D12S391, D18S51, D19S246, D20S480, D21S226, and D22S689. In a total of 488 meioses, 16 isolated genetic inconsistencies in 8 different STRs were observed, whereas no mutations were found at the other loci. The data of five mutations suggested the presence of silent or null alleles due to sequence variation in primer binding site. This could be confirmed for four suspected cases by the use of alternative primer sets and by DNA sequence analyses. Furthermore, this study revealed nine new allelic variants at five different loci. 相似文献
