基因芯片(Gene chip)又称为DNA微阵列(DNA mi-croarray)技术,是新兴的分子生物学研究工具,它是基因分析技术的一项重大突破,使我们能够一次性地对上千种基因进行快速准确的检测。近年来被越来越多的肿瘤生物学家用来分析比较肿瘤组织与相应正常组织之间基因表达的差异,以期发现肿瘤组织中特异表达的基因和药物治疗的靶序列。本文对用基因芯片技术进行肿瘤基因表达研究 Gene chip, also known as DNA mi-croarray technology, is an emerging tool for molecular biology research. It is a major breakthrough in gene analysis technology, allowing us to use thousands of methods at a time. Genes are tested quickly and accurately. In recent years, more and more tumor biologists used to analyze and compare the differences in gene expression between tumor tissues and corresponding normal tissues, in order to find out the specific expressed genes and drug treatment target sequences in tumor tissues. This article uses gene chip technology to study tumor gene expression
