Toward an in vitro system for picornavirus assembly: purification of mengovirus 14S capsid precursor particles.

abstract：:To combat emerging coronaviruses, developing safe and efficient platforms to evaluate viral protease activities and the efficacy of protease inhibitors is a high priority. Here, we exploit a biosafety level 2 (BSL-2) chimeric Sindbis virus system to evaluate protease activities and the efficacy of inhibitors directed ...
