부패시신의 디엔에이형 분석을 위한 효과적인 부검시료 선정에 관한 연구

Analysis of the DNA typing is used an important tools for identification of decomposed cadavers. Recently according to the technology development in the forensics biology, even if the sample is small or decomposition, it becomes possible to identify the individual through new genetic marker and DNA typing techniques. In this experiment, skeletal muscle, costal bone, vessels, achilles tendon, toenails, and molar were collected from 10 decomposed cadavers to analyze the DNA quantitative analysis and the DNA typing. Experimental results showed that the most stable DNA recovery was possible in costa bone, toenails, and skeletal muscles in the quantitative value of DNA. In some samples, more DNA could be recovered from the toenails than from the costal bone. In the DNA typing, the genotype were detected in all samples of costal bone, vessels, and toenails. In addition to the costal bone, DNA analysis of the toenails and other tissue revealed the possibility and should be first collected during DNA typing.
