Abstract:
PURPOSE: An antigen for hemoglutination for swine Japanese encephalitis virus is provided to reduce pollution caused by acetone extraction. CONSTITUTION: A method for preparing antigen for hemoglutination of high concentration for swine Japanese encephalitis virus comprises: a step of inoculating swine Japanese encephalitis virus to a tissue culture cells and planting; a step of freezing culture liquid; a step of thawing the culture liquid and repeating freezing and thawing once; a step of collecting cultured swine Japanese encephalitis virus; a step of inactivating swine Japanese encephalitis virus; a step of concentrating swine Japanese encephalitis virus; and a step of precipitating swine Japanese encephalitis virus by centrifugation.
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.
