Agilent aCGH芯片

  基于基因芯片的比较基因组杂交技术(array-based Comparative Genomic Hybridization, aCGH)可以更加准确地发现疾病相关的染色体的变异,为疾病的诊断和治疗提供极大的帮助,这对高风险人群的健康水平筛查,疾病预防有重要意义。Agilent利用其先进的芯片生产工艺,开发出高性能的aCGH芯片,广泛用于基因的拷贝数检测和染色体结构变化检测。为寻找新的原癌基因或抑癌基因,揭示生物体抗药性的机制及代谢过程中可能发生的基因组变化,发现新的生物标记等提供新的技术。


技术特点:

1.探针覆盖全基因组,包括基因区域(内含子区/外显子区)、基因间区域以及对疾病研究极其重要的亚端粒区域(重复序列除外);

2.高灵敏度和高特异性地检测拷贝数变异CNV、杂合性缺失和单亲二倍体(LOH/UPD);


3.最佳的信噪比和结果重现性;



4.可通过在线系统SureDesign灵活定制芯片,多种规格可选;



5.芯片产品广泛地应用于遗传病、肿瘤、精神障碍、糖尿病等风险筛查和产前筛查等临床研究领域。
