马铃薯病毒 Y（PVY）严重威胁全球马铃薯生产，现有检测方法存在诸多弊端。研究人员开展优化 RT-LAMP 检测 PVY 的研究，该方法在 60°C 仅 30 分钟就能高灵敏、特异地检测 PVY，比 RT-PCR 灵敏 10000 倍，可直接检测粗汁液，对防控 PVY 意义重大。 马铃薯病毒 Y（Potato ...

At-home COVID-19 tests have become an easy way to self-diagnose. But current tests have drawbacks, such as the length of time it takes to get an answer, or how accurately the test can identify a ...

As the coronavirus that causes the COVID-19 disease spreads across the world, the IAEA, in partnership with the Food and Agriculture Organization of the United Nations (FAO), is offering its support ...

本研究针对花椒树胶孢炭疽病潜伏期长、传统检测方法效率低下的问题，开发了基于CYP51C基因的LAMP、巢式PCR和qPCR三种分子检测技术。结果表明，qPCR灵敏度最高(3.1 fg/μL)，巢式PCR稳定性最佳，而LAMP凭借快速(50分钟)、可视化(HNB显色)和低成本优势，成为田间检测的 ...

Respiratory syncytial virus (RSV) was detected easiest when using reverse transcription polymerase chain reaction (RT-PCR) tests in a pediatric population. Reverse transcription polymerase chain ...

The polymerase chain reaction (PCR), invented about three decades ago, soon entered mainstream use thanks to an ongoing series of refinements. One particularly important refinement, introduced about ...
