Abstract

The alkaline protease in the polyhedra preparation of Spodoptera litura nuclear polyhedrosis virus was successfully inactivated by heating at 100C for 20 minutes. SDS-PAGE analysis indicated that heat inactivated polyhedra is composed of major proteins of 31kDa and presumptive its polymer protein of 62kDa. However, this polyhedra was converted into several smaller molecular weight proteins when treated with midgut juice, but not by treatment with heat-inactivated midgut juice.
