A new neutralization method for influenza virus in cell culture.
A novel neutralization method (ELISA-NT) has been developed for simple detection of neutralizing antibodies to influenza virus in which type specific soluble (S) CF antigen produced by unneutralized virus was measured by anti-S immune (probe) serum and enzyme-labelled Clq. Neutralizing antibody activity was determined within 48 h and expressed as a new term, NT% of the quantity of neutralized virus. A good correlation was found between NT% determined by the ELISA-NT method and NT titer by the conventional method in 82 human serum samples (r = 0.941 for type A and r = 0.875 for type B of influenza virus, p < 0.01).
