摘要

Identifying the origin of animal species in manufactured meat products is of considerable economic, religious and sanitary importance. In this study, we developed a multiplex PCR method to simultaneously detect chicken, duck and goose DNA in meat products derived from beef, pork, mutton or quail. The PCR primers were designed based on the sequence of mitochondrial genes of each avian species, and the amplicon sizes were 131, 283 and 387bp for chicken, duck and goose, respectively. The method had no cross-reaction with DNA isolated from beef, mutton, pork or quail, and generated products at a target DNA content as low as 0.05ng, or a target meat content of 1% of total meat weight. Moreover, screening of 24 comme... More
