Abstract:
PURPOSE: A diagnostic method of foot-and-mouth disease using a recombinant FMCV 2C non-structural protein and a monoclonal antibody is provided, thereby more rapidly and accurately diagnosing the foot-and-mouth disease than the prior methods. CONSTITUTION: A gene encoding a recombinant FMCV 2C non-structural protein derived from Korean foot-and-mouth disease virus O/SKR/2000 has the nucleotide sequence of SEQ ID NO: 1. A recombinant vector is prepared by cloning the gene encoding the recombinant FMCV 2C non-structural protein of SEQ ID NO: 1. The recombinant FMCV 2C non-structural protein is expressed by transformation of a cell with the recombinant vector. A hybridoma cell line(KCTC 10137BP) is prepared by introducing the recombinant FMCV 2C non-structural protein into an animal, collecting an immunized cell from the animal and fusing the immunized cell with a cancer cell. A recombinant FMCV 2C non-structural protein specific monoclonal antibody is produced from the hybridoma cell line(KCTC 10137BP). A diagnostic method of foot-and-mouth disease comprises the steps of: (1) diluting the recombinant FMCV 2C non-structural protein specific monoclonal antibody in a coating buffer solution and pouring the diluate on a plate; (2) washing the plate to remove unattached monoclonal antibodies; (3) reacting the recombinant FMCV 2C non-structural protein with the plate; (4) washing the plate to remove unreacted recombinant FMCV 2C non-structural proteins; (5) reacting the testing serum with the plate; (6) washing the plate to remove unreacted testing serum; (7) reacting a conjugate, which binds with an antibody for foot-and-mouth disease virus in the testing serum and has an enzyme, a radioactive material or a fluorescent material, with the testing serum; and (8) measuring intensity of the enzyme reaction, fluorescence reaction or radiation reaction with the conjugate.
Abstract:
PURPOSE: Provided is a device for detecting antibody of Aujeszky's disease. And a method for diagnosing Aujeszky virus more rapidly and correctly using the same is also provided. CONSTITUTION: The device for detecting antibody of Aujeszky's disease is composed of; i) a nitrocellulose membrane (5), absorption pad (3), supporting plate (6), and soaking section (4). The method for detecting antibodies of Aujeszky virus is comprised of the following steps of: i) spreading antigens (1) of Aujeszky virus and anti-swine IgG (2) evenly on the nitrocellulose membrane (5); and ii) reacting the antigens (1) and IgG (2) with antibodies of Aujeszky virus in the soaking section (4), which shows different colors depending on the existence of antibodies.
Abstract:
PURPOSE: Recombinant porcine Aujesky's disease virus provides safe vector vaccine against porcine diseases and can be used to produce effective vaccine against other diseases if antigen of other virus is introduced in it. CONSTITUTION: Recombinant porcine Aujesky's disease virus is useful to prepared a vaccine vector. The vector is constructed by; deletion of K gene; insertion of IL-2 gene; deletion of gI gene; insertion of beta-galactosidase gene as a maker gene; and insertion of foreign gene coding antigen for virus pathogen. Thereby, immunity is improved.
Abstract:
PURPOSE: Provided are a fluorescent vector, which is used for the production of vaccine of porcine Aujesky's disease and a method for selecting recombination virus using the same. CONSTITUTION: A fluorescent vector pHAVE3 is prepared by amplifying pVIII gene corresponding to 5' region of E3 gene of human Adenovirus type II, a partial sequence(27100-28811bp) having 1,712base, before open reading frame of E3 gene being 19kd, a partial sequence(30,851-32,760bp) having 1,910base, after E3-2 polyadenylation signal corresponding to 3' region of E3 gene; cloning them into SpeI of plasmid pGEMT; and inserting BamH I restriction site
