比较基因组杂交 (CGH)是一种将消减杂交和荧光原位杂交 (FISH)相结合的分子细胞遗传学技术 ,可在全部染色体区带上检测基因组间 DNA拷贝数变化并定位。本文综述了 CGH检测胃肠道肿瘤的研究结果及其应用
Comparative genomic hybridization (CGH) is a molecular cytogenetic technique that combines subtractive hybridization and fluorescence in situ hybridization (FISH) to detect and locate DNA copy number changes across genomes across all chromosome bands. This article reviews the results of CGH detection of gastrointestinal tumors and its application
