Abstract EN
There are many PCR-based methods for animal species identification; however, their detection numbers are limited or could not identify unknown species.
We set out to solve this problem by developing a universal primer PCR assay for simultaneous identification of eight animal species, including goat, sheep, deer, buffalo, cattle, yak, pig, and camel.
In this assay, the variable lengths of mitochondrial DNA were amplified using a pair of universal primers.
PCR amplifications yielded 760 bp, 737 bp, 537 bp, 486 bp, 481 bp, 464 bp, 429 bp, and 359 bp length fragments for goat, sheep, deer, buffalo, cattle, yak, pig, and camel, respectively.
This primer pair had no cross-reaction with other common domestic animals and fish.
The limit of detection varied from 0.01 to 0.05 ng of genomic DNA for eight animal species in a 20 µl PCR mixture.
Each PCR product could be further digested into fragments with variable sizes and qualitative analysis by SspI restriction enzyme.
This developed PCR-RFLP assay was sufficient to distinguish all targeted species.
Compared with the previous published related methods, this approach is simple, with high throughput, fast processing rates, and more cost-effective for routine identification of meat in foodstuffs.
