基因芯片及其在突变检测中的应用

基因芯片技术是近年兴起的一项重要的生物技术。作者介绍了基因芯片的起源、发展及其基本操作，并介绍了铺瓦式阵列、直接等位基因特异性荧光检测法、辅助寡核苷酸链、连接酶检测反应、肽核酸技术等几种不同芯片技术在突变检测中的应用，并探讨了基因芯片技术在合理用药中的应用前景。

Gene chip and its use in the detection of mutations

Gene chip is an important biological technology, which is developing quickly recently. In this article, we reviewed the origin, development, basic operation of gene chip. Several kinds of gene chips including tiled array, direct allele specific fluorescence targeting (DAFT) array, labeled auxiliary oligonucleotides array, ligase detection reaction array, and peptide nucleic acid array were introduced as examples for their use in mutation detection. The prospect of the use of gene chip in optimizing drug therapy was also discussed.
