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.

본 발명은 개 부루셀라병의 진단에 있어서, 기존의 개발된 혈청학적 진단법의 단점인 부루셀라(Brucella) 균의 점조성(mucoid)으로 인한 자가응집반응 및 교차반응을 줄이기 위하여 부루셀라 케니스 변이균주(Brucella canis mutant strain Mucoidless)를 이용한 개 부루셀라병의 신속평판응집반응 진단킷트에 관한 것이다. 부루셀라 케니스 변이균주는 부루셀라 케니스 균주(Brucella canis strain)에 비하여 병원성 감소, 비특이적인 응집성 감소, 높은 소수성 등에서 큰 차이를 나타내고, PH 4~6의 범위에서 빠른 시간에 응집하는 결과를 나타내어 현재 피트만모르사에서 사용하고 있는 부루셀라 오비스(B. ovis) 균주보다고 훨씬 신속하게 반응하는 결과를 나타내어 응집반응 원리를 이용한 혈청학적 진단시 비특이반응을 줄이는데 매우 효율적이다. 부루셀라 케니스 변이균주를 이용한 신속평판반응집반응법은 진단효율도 높을뿐 아니라 1시간이내에 검출할 수 있을 정도로 신속하고, 사용방법도 간편함을 특징으로 한다.

PURPOSE: A kit for diagnosing bovine tuberculosis containing monoclonal antibodies and polyclonal antibodies is provided to effectively measure tuberculosis attack. CONSTITUTION: A monoclonal antibody which specifically binds to an epitope is denoted by an amino acid sequence of sequence number 8 in a bovine interferon gamma receptor-binding region. The monoclonal antibody is produced from hydridoma cells(deposit number KCTC 11784BP). A kit for diagnosing bovine contains monoclonal antibody or antigen binding fragment and anti-bovine interferon gamma polyclonal antibody.
Abstract:
PURPOSE: A method for diagnosis of foot and mouth disease and a diagnostic kit are provided, thereby rapidly and accurately diagnosing foot and mouth disease with a small amount of a sample, and easily and rapidly diagnosing foot and mouth disease of domestic animals in the field. CONSTITUTION: The method for diagnosis of foot and mouth disease comprises the steps of: (1) introducing a testing sample into a loading area of a strip; (2) combining a detecting reagent with a marker with a target material in the sample to prepare a complex; (3) developing the complex on a membrane; and (4) measuring the appearance change of a reaction portion having one or more fixing phase selected from antigen, antibody or hapten which is obtainable through the immune reaction from FMDV in a certain region of the membrane. The diagnostic kit comprises a reaction portion(13) having one or more fixing phase selected from antigen, antibody or hapten which is obtainable through the immune reaction from FMDV; a strip(1') having a control portion for determining normal operation on a certain region; a testing sample introducing portion; and a housing with a displaying window(4) for displaying reaction results in the reaction portion(13) and the control portion. on the strip(1').
