Abstract:
PURPOSE: Provided are a genetic recombinant baculovirus and a recombinant spike protein of transmissible gastroenteritis virus(TGEV) manufactured therefrom. And a monoclonal antibody capture enzyme linked immunosorbent assay for detecting the antibody of TGEV using the same protein is also provided, thereby the antibody of TGEV can be rapidly detected. CONSTITUTION: The recombinant spike protein of TGEV is produced by the steps of: isolating and identifying TGEV from pigs died of diarrhea; analyzing the nucleotide sequence of spike protein of TGEV; inserting the TGEV spike gene into the baculovirus gene to produce a recombinant baculovirus(KFCC-11015); infecting the recombinant baculovirus into SF9 cells to express TGEV spike protein. The antibody of TGEV is produced by inoculating the expressed recombinant TGEV spike protein into Guinea pigs. The monoclonal antibody capture enzyme linked immunosorbent assay using TGEV spike protein that is produced from the recombinant baculovirus(KFCC-11015) in Guinea pigs as an antigen is used in detecting the neutralizing antibody of TGEV.

Abstract:
The present invention relates to avian paramyxovirus (APMV)-7 recombinant hemagglutinin-neuraminidase (HN) protein expressed by baculoviruses, and a diagnostic method of APMV-7 using the same. The baculoviruses expressing APMV-7 HN protein according to the present invention, or insect cells transfected with the baculoviruses produce a high concentration of APMV-7 HN protein; easily enable the production of a large number of antigens even in a general laboratory allowing cell culture by using the APMV-7 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-7 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-7 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-7 virus antigen). Therefore, a conventional APMV-7 virus antigen diagnostic reagent can be replaced with the APMV-7 HN protein antigen produced by the present invention even if infectious APMV-7 viruses are not secured.
