Species-specific real-time polymerase chain reaction (PCR) assays using TaqMan probes have been developed for verifying the labeling of meat and commercial meat products from game birds, including quail, pheasant, partridge, guinea fowl, pigeon, Eurasian woodcock and song thrush. The method combines the use of species-specific primers and TaqMan probes that amplify small fragments (amplicons <150 base pairs) of the mitochondrial 12S rRNA gene, and an endogenous control primer pair that amplifies a 141-bp fragment of the nuclear 18S rRNA gene from eukaryotic DNA. Analysis of experimental raw and heat-treated binary mixtures as well as of commercial meat products from the target species demonstrated the suitability of the assay for the detection of the target DNAs.
已开发出针对特定物种的实时聚合酶链反应(PCR)检测方法,使用 TaqMan 探针来验证禽肉和商业禽肉产品的标签,包括鹌鹑、雉鸡、鹧鸪、珍珠鸡、鸽子、欧石鸡和画眉鸟。该方法结合了使用物种特异性引物和 TaqMan 探针,扩增线粒体 12S rRNA 基因的小片段(扩增子<150 个碱基对),以及一个内源性对照引物对,从真核 DNA 中扩增核 18S rRNA 基因的 141 个碱基对片段。对实验原始和热处理的二元混合物以及目标物种的商业肉类产品的分析表明,该检测方法适用于目标 DNA 的检测。
