Objective:
To evaluate the method for species identification by multiplex amplification of mtDNA-HV I, HV II and cytb regions.
Methods:
The bloodstains or muscular tissues of human and 16 kinds of animals were collected. DNA were quantified after extraction. Three pairs of primers were mixed in the same reaction and the PCR amplification products were analyzed by PAGE and silver staining.
Results:
The presence of three bands (278 bp, 358 bp, 425 bp) indicated the samples were from human, while only one band indicated nonhuman origin. The position of the animal's only band is different from the band (358 bp) of human.
Conclusion:
The method of species identification by multiplex amplifying mtDNA-HV I, HV II and cytb regions is simple and sensitive. It is of use for forensic identification.
