目的 为了解成簇规律间隔短回文重复序列(clustered regularly interspaced short pal-indromic repeats,CRISPR)检测技术应用于核酸现场即时检测的研究现状.方法 以"CRISPR""nucleic acid detection""point-of-care testing"或"POCT"为关键词,系统检索公开发表在 PubMed、BioRxiv和MedRxiv数据库中的相关文献.结果 根据纳入、排除标准,共纳入17篇文献,汇总分析CRISPR相关蛋白(CRISPR-associated protein,Cas)酶扩增方法、灵敏度、特异性、检测时间等方面信息.本研究结果显示,结合环介导等温扩增(loop-mediated isothermal amplification,LAMP)或重组酶聚合酶扩增(recombinase polymerase amplification,RPA)等核酸扩增方法后,CRISPR检测技术的灵敏度与实时荧光定量聚合酶反应(real time quantitative polymerase chain reaction,RT-qPCR)相当.结论 CRISPR检测过程在30~100 min即可完成,检测结果可肉眼读取,且检测成本与抗原检测相当,适用于资源匮乏地区进行大规模的核酸现场即时检测.
Systematic review of CRISPR applied to point-of-care nucleic acid detection
Objective To understand the current research status of clustered regularly interspaced short palindromic repeats(CRISPR)applied to nucleic acid detection.Methods In this study,we systematically reviewed related literatures published on databases of PubMed,BioRxiv,and MedRxiv using the keywords"CRISPR","nucleic acid detection","point-of-care testing"or"POCT".Results According to the inclusion and exclusion criteria,a total of 17 publications were selected.We summarized and analyzed the information of CRISPR-associated protein,amplification method,sensitivity,specificity,detection time and other aspects.Results suggested that when combined with nu-cleic acid amplification methods,such as loop-mediated isothermal amplification(LAMP)or recombinase polymerase amplification(RPA),the sensitivity of CRISPR was comparable to real time quantitative polymerase chain reaction(RT-qPCR).Conclusions The process of CRISPR can be completed within 30 to 100 minutes,with results that can be read by the naked eye.Additionally,the cost of detection is comparable to the antigen test,making it particularly suitable for large-scale point-of-care(POC)nucleic acid detection in resource limited areas.
