[Multiple Amplification of 16S RRNA Gene and Cytb Gene in Mitochondrial DNA for Species Identification]

Objective: To establish a fluorescent multiple amplification system of 16S rRNA and Cytb genes located in mitochondrial DNA for species identification.

Methods: A pair of primers of 16S rRNA gene and Cytb gene of the mitochondrial DNA was designed with the software Primer 5.0 to construct a multiple amplification system. The amplified products from human and five species of animals, including cattle, pig, dog, chicken and grass carp were analyzed by 310 Genetic Analyzer.

Results: The amplified products of these samples showed two peaks. The common one was 358bp and the specific one different in unique species was between 231bp and 256bp.

Conclusion: The multiplex amplification system can exactly distinguish the species of human from five common animals.
