Abstract:
PURPOSE: Diagnostic methods of foot-and-mouth disease using recombinant 3ABC non-structural protein expressed in insect cells 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 3ABC 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 baculovirus to be expressed in insect cells is prepared by co-transfection with a recombinant vector containing the recombinant 3ABC non-structural protein gene of SEQ ID NO: 1. The recombinant 3ABC non-structural protein is expressed by infection of the insect cells with the recombinant baculovirus. A hybridoma cell line 3F-11(KCTC 10138BP) is prepared by introducing the recombinant 3ABC non-structural protein expressed in E. coli into an animal, collecting an immunized cell from the animal and fusing the immunized cell with a cancer cell. A monoclonal antibody is produced from the hybridoma cell line 3F-11(KCTC 10138BP). A diagnostic method of foot-and-mouth disease comprises the steps of: (1) diluting the recombinant 3ABC non-structural protein in a coating buffer solution and pouring the diluate on a plate; (2) reacting the testing serum with the plate; (3) 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 (4) measuring intensity of the enzyme reaction, fluorescence reaction or radiation reaction with the conjugate.

Abstract:
The present invention relates to an expression vector comprising a gene encoding a prion protein of Capra hircus and a cell transduced by the vector. The present invention can be used for manufacturing a cell having polymorphism, which represents Capra hircus bred in Korea, and a transduced mouse; and can be effectively used for developing an animal experimental model for studies including diagnosis of prion diseases which include scrapie occurred in goat family animals, and for confirming if domestic TSE diseases interspecifically spread or not.

Abstract:
PURPOSE: A monoclonal antibody for specifically identifying and detecting abnormal prion of chronic wasting disease is provided. CONSTITUTION: A fusion cell line of deposit number KCLRF-BP-00214 produces a monoclonal antibody for detecting abnormal prion of chronic wasting disease. A method for preparing fusion cell line comprises: a step of inoculating a peptide of sequence number 1 to knock-out mouse; a step of isolating B cells from the mouse; and a step of fusing the B cells with mouse myeloma cells. The monoclonal antibody is used for detecting the abnormal prion through western blotting.
