基因芯片技术是建立在杂交序列基本理论上的分子生物学技术,具有高度平行性、多样性、微型性和自动化的特点。被认为是继基因克隆技术、基因测序技术和PCR技术后的又一次革命性的技术突破。已经应用在疾病特别是肿瘤的分化、分型、诊断、发病机制、疗效观察及药物靶标、药物筛选等诸多领域中,并已取得了不少的成就。 Gene chip technology is based on the basic theory of hybridization sequence of molecular biology techniques, with a high degree of parallelism, diversity, miniaturization and automation features. It is considered as another revolutionary technological breakthrough after gene cloning, gene sequencing and PCR. It has been used in many fields such as differentiation, classification, diagnosis, pathogenesis, curative effect observation, drug target and drug screening of diseases, especially tumors, and many achievements have been made.
