Details:
Epitope-blocking ELISA (bELISA): Tables 1, 2 Fig 1, Detection of antibodies to influenza A virus in taxonomically diverse domestic and wild vertebrate species, and mammalian species. The assay was first developed using raccoon and mallard serum. Serum from both naturally exposed and influenza A virus experimentally challenged animals was evaluated. Then sera from 215 birds and 38 mammals was used for further bELISA studies. For the bELISA studies, wells of 96-well ELISA plates were each coated 100 ul (143 mg/ml) of NP-A (IMR-274) in carbonate-bicarbonate buffer (50 mM sodium carbonate, 50 mM sodium bacarbonate, pH 9.6) and incubated overnight at 4 degrees C. See publication for additional assay details.
