The mammalian orthoreovirus (reovirus) outer capsid undergoes a series of conformational changes prior to or during viral entry. These transitions are necessary for delivering the genome-containing core across host cell membranes. This protocol describes an in vitro assay for monitoring the transition into a membrane penetration-active form (i.e., ISVP*).
