Abstract:
본 발명은 돼지생식기호흡기증후군 바이러스 분리를 위한 PAM-pCD163 세포주 및 이를 이용한 백신에 관한 것이다. 본 발명의 PAM-pCD163세포주는 HEK 293세포에 pCD163 유전자를 포함하는 플라스미드로 형질전환시켜 생성된 레트로바이러스를 PAM에 접종하여 pCD163이 안정적으로 세포에서 발현하여 생성된다. 본 발명에 의해, 미생물의 감염이 없는 살아있는 돼지의 폐장으로부터 수거를 해야 기존의 PRRSV 분리시 단점을 해소해 주면서, 수거한 세포의 계대배양이 어렵고(유효계대수가 짧음), 동결보관 후 해동시 감수성이 떨어지는 기존의 PRRSV 분리시 단점도 해소해 줌과 동시에 북미형 PRRSV, 유럽형 PRRSV 모두 분리 및 배양이 가능한 PAM-pCD163세포주 및 이를 이용한 백신이 제공된다.
Abstract:
PURPOSE: A PAM-pCD163 cell line for isolating porcine reproductive and respiratory syndrome(PRRS) virus is provided to develop a vaccine and to prevent PRRS. CONSTITUTION: A PAM-pCD163 cell line is prepared by expressing pCD163 in PAM cells through a retrovirus prepared by transforming plasmid containing pCD163 genes into HEK293 cells. The plasmid is pFB-Zeo-pCD163. A method for preparing the cell line comprises: a step of performing transfection of VSV-G glycoprotein and MMLVgag/pol gene, and a plasmid containing pCD163 into HEK293 cells to prepare retrovirus; and a step of inoculating the retrovirus into the PAM cells.
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.
