  • Recombinant canine parvovirus 2a VP2 and 2b VP2 antigen protein, and use thereof
    Patent number: 11958883
    Abstract: The present invention provides a recombinant expression vector comprising a gene encoding canine parvovirus 2a VP2 or 2b VP2 protein, a recombinant plant into which the vector is transformed, a vaccine composition against canine parvovirus, comprising canine parvovirus 2a VP2 or 2b VP2 protein obtained from the recombinant plant, and a composition for diagnosing canine parvovirus. When the recombinant plant of the present invention is used, canine parvovirus 2a VP2 or 2b VP2 antigen protein can be rapidly produced with high efficiency. Since the composition for diagnosing canine parvovirus according to the present invention uses a recombinant antigen protein, there is no possibility of contamination due to live virus handling, and thus the composition is safe, and the presence or absence of canine parvovirus infection can be rapidly diagnosed from a large amount of samples.

  • RECOMBINANT PORCINE PARVOVIRUS ANTIGENIC PROTEIN AND USE THEREOF
    Publication number: 20220016236
    Abstract: The present invention provides: a recombinant expression vector comprising a gene encoding a porcine parvovirus VP2 protein; a recombinant plant or a recombinant insect cell transformed with the vector; and a vaccine composition for a porcine parvovirus and a composition for diagnosing porcine parvovirus, both of which contain a porcine parvovirus VP2 protein obtained from the recombinant plant or the recombinant insect cell. When the recombinant plant or recombinant insect cell of the present invention is used, the porcine parvovirus antigenic protein can be produced with high efficiency, and the porcine parvovirus antigenic protein production method using the recombinant plant or recombinant insect cell has excellent safety and stability compared with other antigen production methods.
