METHOD FOR MEASURING INFLUENZA B VIRUS

摘要

Disclosed are: a method for measuring influenza B virus by immunoassay, said method enabling the influenza B virus to be detected specifically and with higher sensitivity than methods of the prior art; and an instrument or kit for the abovementioned method. The method for measuring the influenza B virus involves performing an immunoassay on the influenza B virus by a sandwich method in which two types of monoclonal antibodies or antigen-binding fragments of said monoclonal antibodies are used. The two types of monoclonal antibodies specifically react with the 125th to 248th amino acid regions of the matrix protein (M1) of the influenza B virus, and are simultaneously able to bind with the 125th to 248th amino acid regions of M1.
