WebMay 8, 2024 · The cytopathic effect (CPE)-based neutralization test (Nt-CPE) is a common neutralization method for ZIKV. However, this method has some drawbacks, such as being time-consuming and labor-intensive and having low-throughput, which precludes its application in the detection of large numbers of specimens. ... Enzyme-Linked … WebAt the end of the exposure, the Viral ToxGlo assay was used to measure ATP, which serves as an indicator of cell viability. The TCID 50 or 50% cytopathic effect (CPE) is the virus dilution that reduces the measured cell viability by 50%. This value was used for subsequent studies on the potency of antiviral agents.
