Objective: To establish a practical, accurate and convenient DNA molecular genetic marker technique for the identification of Testudinis Carapax et Plastrum. Methods: The mtDNA were extracted from Testudinis Carapax et Plastrum and its adulterants by salting-out method respectively. Bioinformatics technology was used to explore the identification and characterization of mitochondrial cytobchrome b gene from Chinemys revisii and other turtle species. A pair of allele-specific PCR primers were designed according to the cyt b gene, the PCR amplification were performed with mtDNA extracted from Testudinis Carapax et Plastrum and its adulterants. Results: The pure and intact mtDNA was extracted from Testudinis Carapax et Plastrum and its adulterants. The pair of allele-specific primers could only amplify the cyt b gene of Chinemys revisii with amplification of 319 bp. Conclusion: The primers are specific to Chinemys revisii mtDNA and could be used to discern Testudinis carapax et Plastrum from its adulterants
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
