Abstract:
A recombinant protein of avian influenza virus and a diagnostic composition of avian influenza containing the same protein are provided to mass produce the antigen for diagnosis of avian influenza cheaply, so that the disease caused by avian influenza is prevented. The method for producing the recombinant nucleus protein of avian influenza virus comprises the steps of: (1) amplifying the gene encoding nucleocapsid having the nucleotide sequence of SEQ ID NO:1 as a common protein of MS96 strain with PCR, and cloning the PCR amplified gene into the TA cloning vector; (2) re-isolating the NP gene inserted into the TA cloning vector with a restriction enzyme EcoR I, and inserting the isolated NP gene into the baculovirus transition vector pBacPAK8 to prepare the baculovirus transition vector pBacAINP; (3) co-transfecting the Sf21 cell with the baculovirus and the transition vector pBacAINP to a recombinant baculovirus(rAINP) expressing the avian influenza virus NP protein; and (4) verifying the expression of avian influenza virus NP(nucleus protein) in the Sf21 cell by using a monoclonal antibody specific to the avian influenza virus NP.

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.

Abstract:
PURPOSE: A primer and kit for detection and pathotype-diagnosis of Newcastle disease virus are provided, thereby simultaneously detecting the Newcastle disease virus and diagnosing pathotype of the Newcastle disease virus, so that death rate of domestic animals by the Newcastle disease virus can be reduced. CONSTITUTION: The primer for detection and pathotype-diagnosis of Newcastle disease virus is selected from a primer set having the nucleotide sequences of SEQ ID NO:1 and SEQ ID NO:2, a primer set having the nucleotide sequences of SEQ ID NO:2 and SEQ ID NO:3, and a primer set having the nucleotide sequences of SEQ ID NO:1, SEQ ID NO:2 and SEQ ID NO:3. The method for pathotype-diagnosis of Newcastle disease virus comprises the steps of: (1) obtaining RNA from a sample; (2) carrying out reverse transcription of the RNA to obtain cDNA; (3) PCR amplifying the cDNA using the primer; (4) subjecting the PCR product to electrophoresis; and (5) deciding the Newcastle disease virus as non-pathogenic virus when the PCR product shows a band of 379bp, or as pathogenic virus when the PCR product shows two bands of 379bp and 204bp.
