Expression of hepatitis B virus core and precore antigens in insect cells and characterization of a core-associated kinase activity.

abstract：:It has recently been shown that RNA from the bottom component of cowpea mosaic virus is capable of self-replication in cowpea mesophyll protoplasts, providing a tool for the investigation of the contribution of each RNA strand toward viral multiplication. Evidence is presented here, using this system, to show that the...
