Abstract:
To detect STR genotypes of degraded DNA from decomposed tissues. The PCR apmlified products of 40 degraded DNA samples, which were purified from decomposed muscles after death for 1~6 weeks, were separated by denaturing polyacrylamide. The genotypes were analyzed by 377 DNA sequencer and 2 fluorescence-based multiplex amplification systems which contain 12 STR loci and lsex locus. The specific PCR products of 12 STR loci and 1 sex locus of the 40 samples were typed precisely and rapidly. The method described here is very useful in forensic case works, especially for the seriously degraded DNA samples.
