CRISPR技术的问世掀起了生物技术领域的革命。因其高灵敏度、高特异性、以及反应温度温和等优点,CRISPR技术被称为“下一代”诊断技术,近来CRISPR技术已经被广泛应用于分子诊断领域。然而,目前的CRISPR检测,仍然需要结合核酸预扩增才能达到高灵敏度,这不可避免地会由于交叉污染和潜在的扩增偏差而带来假阴性或假阳性结果。
我院王丽课题组于近日发表于Biosensors and Bioelectronics(IF 12.54)期刊的论文,在前期研究工作的基础上提出了免扩增CRISPR核酸检测策略,以解决此问题。论文题为:Rapid and sensitive detection of Ebola RNA in an unamplified sample based on CRISPR-Cas13a and DNA roller machine。http://dx.doi.org/10.2139/ssrn.4058791。硕士研究生杭晓敏为论文的第一作者。
王丽副教授团队长期致力于分子诊断方法和技术的开发和应用研究工作。
