Fig 1. Reactivity of CT302 IgG1 to H3N2 trimeric HA.

Fig 1

(A) After recombinant trimeric HA protein was coated onto 96-well plates, CT302 IgG1 (■) or negative-control anti-respiratory syncytial virus IgG1 (□) was incubated in wells as primary detection antibodies. Antibody bound to the recombinant His-tagged trimeric HA protein was detected with an HRP-conjugated anti-human IgG by addition of HRP substrate. Results represent the mean±S.D. obtained from duplicate wells per each condition. (B) Recombinant His-tagged trimeric HA proteins from H1, H3, and H5 strains were resolved by SDS-PAGE and transferred to nitrocellulose membranes, which were probed with CT302 IgG1 or anti-His antibody. (C) Amino acid sequences in the VH and VL regions of CT302 IgG1. HA, hemagglutinin; HRP, horseradish peroxidase.
