[Microarray for diagnostics of human pathogenic influenza A viruses subtypes]

An oligonucleotide microchip was developed for diagnostics of human pathogenic Influenza A viruses subtypes. It contains discriminating probes for H1-, H2-, H3-, H5-, H7- and H9-subtypes of hemagglutinin and for N1-, N2-, and N7-subtypes of neuraminidase. The additional set of probes was used for M-gene of Influenza A viruses definition. Microchip was tested on samples pathogenic H5N1 avian influenza viruses, pandemic H1N1 swine influenza viruses and seasonal H1N1 and H3N2 influenza viruses. The microchip can be used for the analysis of both cultured strains and clinical specimens.
