WebLaboratory diagnosis of viral infections can be carried out by many methods. These methods include (a) demonstration of virus-induced cytopathic effects (CPEs) in the cells, (b) direct detection of viruses, (c) virus isolation and viral assays, (d) detection of viral proteins and other enzymes, (e) detection of viral genome, and
WebThe assays below have been developed to cover a wide spectrum of the SARS-CoV-2 life cycle, including both viral and human (host) targets. This list will be updated continuously as more assays are developed and screened, and all protocols and screening datasets will be made freely available below. WebThis assay can be used to detect the antiviral activity of the test drug and cytopathicity can be expressed microscopically as 0 = No CPE; 1 = 0–25%; 2 = 25–50%; 3 = 50–75%; 4 = 75–100%. This initial evaluation is usually done at a twofold concentration (with a 10-fold difference, e.g., 1 and 10 ng/ml or μg/ml).
