title: [Expression of hepatitis A virus procapsids in the insect cells infected by recombinant baculovirus].
abstract: The recombinant baculocvirus containing genome P1-2A-P3 of hepatitis A virus (HAV) was constructed and used for infecting the Sf9 insect cells. It was demonstrated that the deletion of 2BC from HAV polyprotein and the insertion of a new 3C protease cleavage site between P1-2A and P3 did not interfere with the processing of polyprotein or with forming the 70S-procapsids. The identity of the protein contents as well as of morphological and antigen characteristics, obtained in Sf9-cells, to HAV empty capsids, which take shape in the infected mammal cells, proves that it is possible to use them in making the vaccine and diagnostic preparations.
