Abstract:
본 발명은 티미딘 키나제(Thymidine kinase; 이하 "TK"라 한다) 선발(selection)을 이용하는 유전자 재조합 바이러스 선발과정을 통하여 국내분리 돼지 오제스키병 바이러스 유전자 중 병원성과 관련된 3종의 유전자인 UL21, TK 및 gE 유전자를 제거하고, 그 부위에 외부 유용 유전자를 대신 삽입하여 제조한 바이러스 벡터 시스템에 관한 것이다. 본 발명에서는 상기에서 제조한 바이러스 벡터 시스템을 사용하여 재조합 바이러스 스크리닝의 어려움을 극복하고 간편하게 재조합 돼지 오제스키병 바이러스를 작성할 수 있다. 돼지 오제스키병 바이러스, 유전자 재조합, 벡터, 티미딘 키나제, 약제 선발, TK 유전자, UL21 유전자, gE 유전자
Abstract:
PURPOSE: A porcine circovirus 2 (PCV2) capsid protein is provided to produce a large amount of antigens, to diagnose circovirus 2 capsid antibody, and to produce a vaccine. CONSTITUTION: A method for detecting a porcine circovirus antibody comprises a step of using a porcine circovirus 2 capsid protein as an antigen. The capsid protein has an amino acid sequence of sequence number 2. The amino acid sequence is encoded by a base sequence of sequence number 1. The method is performed by a fluorescent antibody test or enzyme immunoassay. A vaccine for preventing porcine circovirus 2 contains the capsid protein as an antigen.
Abstract:
PURPOSE: An immortalized porcine alveolar macrophage and a method for detecting and proliferating infectious virus using the same are provided to develop a diagnostic method and a vaccine. CONSTITUTION: An immortalized porcine alveolar macrophage is prepared by transfection of an expression vector containing hTERT(human telomerase reverse transcriptase) gene of sequence number 1 to porcine alveolar macrophage cell line. The immortalized porcine alveolar macrophage cell line is used for detecting porcine alveolar macrophage infectious virus. The virus includes porcine reproductive respiratory syndrome virus, porcine circovirus, animal and human influenza virus, porcine cytomegalo virus, vesicular stomatitis virus, aujeszky virus, swine fever virus, or vaccinia virus.
Abstract:
PURPOSE: A diagnostic kit for rapid detection of rabies antibodies is provided to rapidly detect the existence according to rabies vaccination within 20 minutes without expensive equipment and to reduce the generation of rabies. CONSTITUTION: A diagnostic kit for rapid detection of rabies antibodies using immunochromatography has a nitrocellulose membrane(30) containing a test line(40) and a control line(50) on a backing card(70). A conjugate pad is overlapped at one side of the nitrocellulose membrane. A sample pad(10) is overlapped on the conjugate pad. An adsorbent pad(60) absorbing blood serum in which the reaction is completed on a backing card is installed at the other side of the nitrocellulose membrane.
