[DNA examination for criminal investigation].
The main purpose of DNA examination in a criminal investigation is identification from biological specimen material (sample). Occasionally, DNA genotyping of the sample in which decomposition, pollution, mixture, degeneration, etc., have progressed is requested for identification. In addition, in cases of a small amount of sample, it is not possible to conduct checks many times. The Police Agency in Japan introduced the multiplex PCR system that can detect 15 kinds of STR genotyping and perform sex determination simultaneously using only a small amount of DNA.
