KIT FOR DETECTING HIGHLY PATHOGENIC AVIAN INFLUENZA VIRUS SUBTYPE H5N1

摘要

Disclosed are an immunoassay kit and an immunoassay method for detecting highly pathogenic avian influenza virus subtype H5N1 rapidly, conveniently and specifically. Also disclosed are an immunochromatographic detection kit and an immunochromatographic detection method for detecting the virus subtype H5N1 rapidly, conveniently and specifically. It is found that a monoclonal antibody 4G6 produced by using the virus subtype H5N1 as an immunogen does not react with the a subtype H5N2 virus or a subtype H5N3 virus and reacts only with a subtype H5N1 virus specifically. It is also found that only an avian influenza virus subtype H5N1 can be detected specifically by an immunoassay utilizing the monoclonal antibody 4G6. It is further found that the sensitivity of the detection of immunochromatography can be increased by adding a nonionic surfactant and a water-soluble vinyl polymer having a polar group containing an oxygen atom and a nitrogen atom to a developing solution to be used in the immunochromatography.
