We report a universal and signal-on HCR based detection platform innovatively coupling the CRISPR-Cas12a system with HCR. By using this CRISPR-HCR pathway, we can detect different targets by only changing the crRNA. The CRISPR-HCR platform coupling with an upstream amplifier can achieve a practical sensitivity as low as ∼aM of ASFV gene in serum.
我们报告了一种基于杂交链式反应（HCR）的通用且信号开启的检测平台，该平台创新性地将CRISPR-Cas12a系统与HCR耦合。通过使用这种CRISPR-HCR途径，我们仅通过改变crRNA就能检测不同的靶标。与上游放大器耦合的CRISPR-HCR平台在血清中对非洲猪瘟病毒（ASFV）基因可实现低至约aM的实际检测灵敏度。
