DNA(脱氧核糖核酸)防伪技术
DNA anti-counterfeit techniques

  DNA(t琦JO四ngh6tanghesuan)for怕M旧i」ishu〕叭(脱权核精核酸)防伪技术(DNA anti~-terfeit techniq”eS)它的核心在于DNA的一级结构即碱基序列的多样性,任何生物来源的DNA片段理论上均可作为防伪DNA。由于生物特别是高等动、植物的基因组巨大,超过IJ一1012碱基对(ha),而用于防伪DNA分子仅为数百娜,可供选择的余地极大。DNA作为遗传物质,生物物种乃至于个体之间,其DNA序列也不完全相同。 DNA进行商品防伪在世界范围尚未见诸报道,这主要是由于传统DNA检测过于繁琐复杂,生产成本与检侧昂贵。目前中国已有廉价克隆化生产的防伪DNA分子。由于序列已知,可以依据特异性聚合酶链反应(PCR)方法检侧,就汉刃饰大小的DNA分子而言,其检测极限可达10一’.9,只要在商品中加人微量DNA,即可实现检侧。DN人在商品防伪应用中十分简单,胶水、油呈、酒、化妆品中引人DNA及检测方法,不改变原工艺和技术要求。同时,DNA是无毒无害的生物大分子,食品、药品、饮料等生产工艺中,以水为媒介掺人DNA也是十分便利的。由于DNA的稳定,在化石标本中的DNA迄今仍能采用PCR检测为明证,一般商品的防伪采用DNA理论上不存在保存期的问题。 (张燕辰)
