ABSTRACT
The structural protein genes of polyomavirus were expressed in the baculovirus system, and the proteins were found to assemble into capsid-like particles capable of packaging insect cell DNA. Recombinant capsid-like particles could be produced that were composed of the various structural proteins (VP1, VP1/2, VP1/3 and VP1/2 + VP3). Laser scanning confocal microscopy was used to determine if the various capsid-like particles could infect (enter) mouse 3T6 cells. Each of the various capsid-like particles was equally capable of cell entry as determined by indirect immunofluorescence confocal microscopy.
