摘要:

目的:建立一种快速、特异、灵敏的鸭源性成分检测方法。方法:以鸭细胞色素C氧化酶Ⅲ(COⅢ )基因序列为靶位点设计引物,进行聚合酶链式反应扩增,建立鸭源性成分检测方法;以常见畜禽肉,包括羊肉、牛肉、鸡肉、鹅肉、猪肉、兔肉、马肉、鹿肉等参考动物物种进行特异性检测;以50 mg/kg羊肉DNA作为稀释液,对鸭肉DNA进行梯度稀释,检测灵敏度。结果:该方法能够有效的对鸭源性成分进行快速检测,具有较强的特异性,灵敏度较高(0.1 μg/kg),且羊肉成分的存在对鸭肉灵敏度检测没有影响,可以快速、准确检测畜肉食品中掺杂的鸭源性成分。

Abstract:

This report describes a rapid polymerase chain reaction (PCR) method to detect duck-derived DNA by using
primers corresponding to the duck COⅢ gene. The method was duck specific, free from interference from lumb DNA (50
mg/kg). Its sensitivity was sufficient to detect as low as 0.1 μg/kg duck-derived materials. It can provide a rapid and accurate
way to identify duck-derived materials adulteration in meat products without interference of mutton DNA.

Key words: duck-derived materials, cytochrome oxidase Ⅲ (COⅢ ) gene, polymerase chain reaction (PCR), detection
