CONSTRUCT OF SWINE VESICULAR DISEASE VIRUS LIKE PARTICLE USING GENETIC ENGINEERING AND THE METHOD FOR MANUFACTURING THEREOF

摘要

The present invention relates to a swine vesicular disease virus-like particle prepared by a gene recombination technique, as well as a preparation method thereof. More particularly, the invention relates to a method for preparing a swine vesicular disease virus-like particle, wherein the structural protein precursor (Pl) gene and 3CD protease gene of swine vesicular disease virus are inserted simultaneously into a baculovirus expression vector and are expressed in insect cells, so that the expressed 3CD protease enzyme digests the structural protein precursor into individual proteins which then form the capsid of swine vesicular disease virus by an self-assembly process.
