title: ELISA detection of influenza haemagglutinin depends on its molecular environment.
abstract: Two ELISA techniques (indirect and sandwich) were used for detection of influenza HA in three HA-containing specimens: whole influenza virus, HA + NA, isolated HA. Adsorptive and antigenic properties of the HA were found to depend on its physicochemical state and molecular environment.
