WebJul 27, 2024 · The TCID 50 value is determined when the cytopathic effect or cell viability assay read-out appear the same for a dilution in 3 separate readings. An example of the application of cell viability/toxicity assays for the evaluation of viral cytopathic effects can be found in the AN 363: Viral cytopathic effects measured in a drug discovery screen. WebCytopathic effects can be assayed in varied ways. Plaque Reduction Neutralization Testing (PRNT) has long been considered the standard for viral assays, but other assays can be used to measured cell viability or cell death such as MTT, MTS or Trypan Blue (see sample protocols 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).
