Hyperbranched rolling circle amplification (HRCA)-based fluorescence biosensor for ultrasensitive and specific detection of single-nucleotide polymorphism genotyping associated with the therapy of chronic hepatitis B virus infection.

检测与药物作用相关的特异性基因为个体化医疗提供科学指导。本文以慢性乙型肝炎病毒（HBV）治疗相关单核苷酸多态性（SNP）基因分型检测为例，基于超支化滚环扩增（HRCA）构建了一种高灵敏、高选择性荧光生物传感器。单碱基突变DNA（mutDNA）可与特异性设计的鉴别锁式探针完全杂交，并启动HRCA反应；随后释放大量双链DNA序列，加入S...
