简介：
Overview
This study focuses on the identification and characterization of small molecule antivirals against Bluetongue virus (BTV) using various assays. Three key assays, including the cytopathic effect (CPE)-based assay, dose-response assay, and Time-of-Addition (ToA) assay, are developed and optimized to evaluate antiviral efficacy and cytotoxicity.
Key Study Components
