Determination of analytical specificity and sensitivity The specificity of the H5 dot ELISA was tested with a total of 100 HPAI H5 strains isolated from humans and avian species GW-572016 chemical structure and 40 non-H5 subtype influenza virus strains from different regions and years, including 26 seasonal influenza virus strains (H1N1, H3N2, and B subtypes) and 2 pandemic influenza virus strains circulating in humans. Viruses of H5 or HA subtypes not available in our laboratory were rescued by reverse genetics with the six internal genes from A/Puerto Rico/8/34. The reactivity and specificity of the H5 dot-ELISA
were examined with 200 ul of PBS containing the H5 strains adjusted to an HA titer of 8. Non-H5 viruses with HA titers of 16 were used in order to eliminate false-positive results. Virus strains listed in Table 5 and 6 were tested in the laboratory and the rest strains were studied at the sites of those virus donors. The dot ELISA rapid test with 4C2 and 6B8 can successfully detect all the 100 H5 virus strains from different clades, YAP-TEAD Inhibitor 1 cost covering clades 1, 2.2, 2.3, 0, 7, 4, and 8, and representative H5 Indonesia isolates, which belong to clade 2.1. No cross-reactivity was observed for any
of the non-H5 subtype viruses tested. Other avian viruses such as Newcastle Disease (ND), Infectious Bursal disease (IBD), were also tested to be negative with the H5 dot ELISA.
