Peptide Tools to Study Influenza Virus

About the Influenza Virus

Influenza viruses belong to the orthomyxoviridae family. These are enveloped viruses with a segmented, negative-sense, single- stranded RNA genome. Only orthomyxoviridae Influenza type A and B cause disease in humans. Their main antigenic determinants are the two transmembrane proteins hemagglutinin (‘H’ or ‘HA’) and neuraminidase (‘N’ or ‘NA’).
The combinations of specific variants of the H (H1-H18) and N (N1-N11) proteins are used to classify Influenza A viruses into subtypes. The standard WHO nomenclature for a given human influenza virus comprises the genus (‘A’), the geographical site where they were first identified (e.g. Hong Kong), a serial number and the identification year (e.g. 1/1968), and finally the H and N variants.

JPT offers a range of highly relevant Influenza virus-specific antigen peptides, PepMix™ peptide pools and PepStar™ peptide microarrays.
