ＤＮＡ阵列 (ＤＮＡＡｒｒａｙ)是在基因转录水平探测疾病发生发展相关事件以及确定疾病易感基因或保护性基因多态性的一种工具〔1、2〕。ＤＮＡ阵列技术的基本原理是 :单链ＤＮＡ可与硝酸纤维膜牢固结合 ,并与互补ＲＮＡ杂交。首先广泛采用的固相支持物杂交技术是Ｓｏｕｔｈｅ
DNA Arrays (DNAArray) is a tool for detecting events related to the development of a disease at the gene transcriptional level and for identifying disease susceptible genes or protective genetic polymorphisms [1,2]. The basic principle of DNA array technology is that single-stranded DNA can be strongly bound to a nitrocellulose membrane and hybridized with complementary RNA. The first widely used solid-phase support hybridization technique is Southe
