Receptor-binding profiles of wild-type influenza A(H9N2) viruses from Pakistan. Wild-type UDL-01/08 virus SKP and 3 contemporary wild-type viruses were generated by using reverse genetics, and receptor-binding to 3 receptor analogs was assayed by using biolayer interferometry. Sugars tested were 3SLN(6Su) (green), 6SLN (blue), and 3SLN (red). A) H9N2 A/chicken/Pakistan/UDL-01/2008; B) H9N2 A/chicken/LH-55/2014; C) H9N2 A/chicken/SKP-989/2015; D) H9N2 A/chicken/SKP-827/2016.
