Mitochondrial DNA (mt DNA) sequence analysis has been a useful tool for species identification of animals and human individuals. Two hypervariable regions (HV1 and HV2) in control region of mitochondrial genome were analyzed for human individual identification. In case of animal species identification, several genes on mt DNA such as cytochrome b (cytb), RNAs, cytochrome oxidases (CO) were used. In this study, co-amplification of HV1 and cytb was carried out in order to check the contamination of animal DNA and to verify the human DNA. The primer sets used in PCR were H15997/L16236 for HV1 and H14724/L15149 for cytb. PCR products for HV1 and cytb were 239 bp and 425 bp, respectively. The appearance of two bands on agarose gel implied the DNA came from human, however the single band of cytb gene represented the non-human animal DNA.
