The Study of Some Physico-Chemical Properties of the Polyhedrin of Heliothis armigera Nuclear Polyhedrosis Virus VHA-273 Strain
Hua Zong Normal University
Polyhedra were extracted from the cadavers of Heliothis armigera infected with VHA-273 strain of Heliothis armigera nuclear polyhedrosis virus. Observation under electron microscope showed that the polyhedra consisted of mNPV (90%) and sNPV(10%). The purity of polyhedrin purified by serial procedures was confirmed by immunological and electrophoresis methods. When the isoelectric point of the polyhedrin was determined by isoelectric focusing electrophoresis, 7bands appeared, with a major band at p15.78±0.02...
