WebFeb 26, 2024 · Cytopathicity assays for primary screening and concentration-response studies The inhibition of the SARS-CoV-2 cytopathic effect was measured using the assay workflow summarized in Fig. 1 12.... WebHere, we provide the detailed protocol for the cytopathic effect (CPE) assay and the plaque assay for human coronaviruses 229E (HCoV-229E), HCoV-OC43, and HCoV-NL63, to identify novel antivirals against HCoVs. Neutral red was used in the CPE assay, as it is relatively inexpensive and more sensitive than other reagents.

A titer is defined as a given number of infectious viral units per unit volume, and an infectious unit is the smallest amount of virus that produces recognizable effects [e.g., cytopathic effect (CPE), dot blot immunoreactivity].
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).
