Dengue virus (DENV) is listed as one of the NIAID Category A priority pathogens. Dengue disease is endemic in most tropical countries, with an estimated 2.5 billion people living in areas at risk of DENV infection. Due to the lack of vaccines and antiviral drugs, it is now a huge public health burden around the world. In order to screen large compound libraries for the identification of novel antivirals targeting DENV, it is essential to develop a high throughput screening (HTS) amenable assay. Here, we present the development, optimization and validation of a cytopathic effect-based assay against Dengue virus serotype-2 (DENV-2). The assay conditions, including cell culturing conditions, DMSO tolerance and the multiplicity of infection, were optimized in both 96- and 384-well plates. Assay robustness and reproducibility were determined under the optimized conditions in 96-well plate, including Z'-value of 0.71, signal-to-background ratio of 6.88, coefficient of variation of 6.3
