目前针对严重急性呼吸综合征冠状病毒2型(SARS-CoV-2)抗体的血清学检测主要采用酶联免疫吸附试验、荧光微粒免疫试验或侧流试验的形式,这些方法要么费力、昂贵,要么缺乏足够的灵敏度和可扩展性。在这里,我们提出了一种快速,低成本,基于溶液的检测血清,血浆,全血和在较小程度上唾液中的抗体的开发和验证,使用合理设计的分裂荧光素酶抗体生物传感器。这种新的检测方法可在30分钟内生成定量结果,大大降低了2019冠状病毒病(COVID-19)抗体检测的复杂性并提高了其可扩展性。该检测试剂盒非常适用于护理点、广泛人群检测和低资源环境中的应用,用于监测宿主对疫苗接种或病毒感染的体液反应。
Current serology tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies mainly take the form of enzyme-linked immunosorbent assays, chemiluminescent microparticle immunoassays or lateral flow assays, which are either laborious, expensive or lacking sufficient sensitivity and scalability. Here we present the development and validation of a rapid, low-cost, solution-based assay to detect antibodies in serum, plasma, whole blood and to a lesser extent saliva, using rationally designed split luciferase antibody biosensors. This new assay, which generates quantitative results in 30 min, substantially reduces the complexity and improves the scalability of coronavirus disease 2019 (COVID-19) antibody tests. This assay is well-suited for point-of-care, broad population testing, and applications in low-resource settings, for monitoring host humoral responses to vaccination or viral infection.
