Abstract:
PURPOSE: A scFv gene of monoclonal antibody 4G31 and a recombinant protein expressing the same are provided to neutralize RAV and to reduce and diagnose rabies virus. CONSTITUTION: A 4G31 scFv(single chain variable fragment antibody) gene which specifically neutralizes rabies virus has an amino acid sequence and a base of sequence number 16. The 4G31 scFv gene is a 4G31 monoclonal antibody containing a gene encoding a heavy chain variable region(VH) and a light chain variable region(VL). An expression vector expresses the 4G31 scFv gene. A recombinant protein is prepared by expressingthe 4G31 scFv gene in E.coli using the expression vector. A therapeutic agent for rabies virus contains the recombinant protein expressed from the 4G31 scFv gene.

Abstract:
A kit and a method for diagnosing a porcine epidemic diarrhea virus antigen are provided to diagnose the antigen conveniently and rapidly without a special testing equipment in a farm or a laboratory field. A kit for diagnosing a porcine epidemic diarrhea virus antigen is characterized in that a conjugate of a monoclonal antibody 6G15(deposition no. KCTC 10996BP) coupled to nucleocapside 58kDa of an epidemic diarrhea virus and a gold particle is attached to a reaction position of the porcine epidemic diarrhea virus antigen on a strip and a monoclonal antibody 9D11(deposition no. KCTC 10997BP) is attached to a position different from the coupling portion of the porcine epidemic diarrhea virus antigen and the monoclonal antibody 6G15. A method for diagnosing the porcine epidemic diarrhea virus antigen comprises the steps of: (a) loading a sample onto a detection pad on a strip; (b) reacting the conjugate of the monoclonal antibody 6G15 coupled to nucleocapside 58kDa of the epidemic diarrhea virus and the gold particle with the porcine epidemic diarrhea virus antigen in the sample; and (c) reacting the porcine epidemic diarrhea virus antigen, the monoclonal antibody 9D11 and the reaction product obtained from the step(b).
