WebThe Viral ToxGlo™ Assay is a simple “add-mix-measure” homogeneous assay for monitoring viral-induced cytopathic effect. It offers a highly sensitive, precise and quantitative method of measuring … CPEs are important aspects of a viral infection in diagnostics. Many CPEs can be seen in unfixed, unstained cells under the low power of an optical microscope, with the condenser down and the iris diaphragm partly closed. However, with some CPEs, namely inclusion bodies, the cells must be fixed and stained then viewed under light microscopy. Some viruses' CPEs are characteristic and therefore can be an important tool for virologists in diagnosing an infected animal or human…
