Abstract:
본 발명은 구제역 바이러스 7가지 혈청형 진단용 프라이머 세트 및 이의 용도에 관한 것이다. 본 발명의 구제역 바이러스 검출용 프라이머 세트는, 낮은 농도의 시료만으로도 7가지 구제역바이러스의 혈청형을 검출할 수 있어 민감도가 높고, 특이도가 우수하다. 또한, 본 발명의 구제역 바이러스 검출용 프라이머 세트를 이용한 RT-LAMP법을 이용하면 기존의 진단법과는 달리 등온조건에서 유전자 증폭이 이루어지기 때문에 검사시간을 단축할 수 있으며, 저가의 장비로도 반응이 가능하다. 따라서, 고가의 장비, 시약 및 전문인력이 확보되지 않은 진단실이나 현장에서도 구제역 바이러스를 신속하고 효과적으로 진단할 수 있는 바, 국내외 바이러스 진단 시장에서 용이하게 활용될 수 있다.
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.

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:
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.
