Abstract:
The present invention relates to avian paramyxovirus-9 (APMV-9) recombinant hemagglutinin-neuraminidase (NH) protein expressed by baculoviruses, and a diagnostic method of APMV-9 using the same. The baculoviruses expressing APMV-9 HN protein according to the present invention, or insect cells transfected with the baculoviruses produce a high concentration of APMV-9 HN protein; easily enable the production of a large number of antigens even in a general laboratory allowing cell culture by using the APMV-9 HN protein; and enable the production of an antigen diagnostic reagent within a week by an insect cell culture method, thereby having an effect of shortening the production period of the antigen diagnostic reagent by at least one week. In addition, an APMV-9 HN protein antigen produced by the present invention has hemagglutination ability for erythrocytes of a chicken and thermal stability; has exhibited a specific HI reaction by APMV-9 immune serum; and also has an effect of exhibiting the same test result in comparison with a HI reaction test result from a conventional antigen (APMV-9 virus antigen). Therefore, a conventional APMV-9 virus antigen diagnostic reagent can be replaced with the APMV-9 HN protein antigen produced by the present invention even if infectious APMV-9 viruses are not secured.
Abstract:
The present invention relates to a recombinant virus expression vector including a gene which encodes hemagglutinin-neuraminidase (HN) protein of avian paramyxovirus-3 (APMV-3); to recombinant insect cells which transformed by the vector and expressing the HN protein of APMV-3; and to a diagnostic composition for APMV-3 including the recombinant antigenic HN protein of APMV-3 expressed by the recombinant insect cells, a diagnostic kit including the HN protein, and a diagnostic method using the HN protein. The diagnostic composition for APMV-3 according to the present invention is safe without the possibility of contamination caused by treatment of live viruses and has an excellent effect of quickly and accurately diagnosing whether there is infection with APMV-3 from a large number of samples.
