Independent and disparate evolution in nature of influenza A virus hemagglutinin and neuraminidase glycoproteins.

Proceedings of the National Academy of Sciences of the United States of America - 1 Jan 1990

Kilbourne E D, Johansson B E, Grajower B

Abstract excerpt

The hemagglutinin (HA) and neuraminidase (NA) external glycoprotein antigens of H1N1 and H3N2 subtypes of epidemiologically important influenza A viruses prevalent during recent decades were subjected to intensive antigenic analysis by four different methods. Prior to serological analysis with po...
