Figure 1 Binding of stalk-reactive antibodies to group 2 HAs.
Binding of stalk-reactive antibodies 12D1 and CR8020 and H3 antiserum to recombinant soluble Wisc05 HA without (w/o T4 trim. domain, black lines) or with (w/T4 trim. domain, red line) trimerization domain.
Krammer, F., Margine, I., Tan, G. S., Pica, N., Krause, J. C., & Palese, P. (2012). A carboxy-terminal trimerization domain stabilizes conformational epitopes on the stalk domain of soluble recombinant hemagglutinin substrates. PloS one, 7(8), e43603.

Figure 2 mAb 12D1 reacts with the LAH of HA2.
Lysates from 293T cells were transfected with pCAGGs-GFP or pCAGGs-GFP HA2 76–130, incubated with mAb 12D1, and pulled down with protein G beads. Pulled-down fractions were blotted with mAb 12D1 or rabbit anti-GFP. Arrows indicate location of the amino acid 76–130 region–GFP fusion protein. Anti-mouse HRP used to detect 12D1-binding reacts with the mouse Ig heavy and light chains within the pulled-down fraction.

Figure 3 Anti-H3 mabs in microneutralization assay.
Neutralization of virus expressing the HA from either (A) A/Hong Kong/1/1968 virus or (B) A/Panama/2007/1999 virus. mAb XY102 is specific for A/HK/1968 virus. Purified mouse IgG was used for the negative control.

Figure 4 Activity of anti-H3 mabs in plaque reduction assay on MDCK cells.
mAb 12D1 neutralize all H3 viruses tested by plaque reduction assay but not representative H1, H4 or H7 viruses. Purified mouse IgG was used for the negative control. The plaque reduction assays were performed multiple times and with each new antibody preparation. Data shown are from a single representative experiment.

SDS-PAGE
Figure 1 Anti-IAV HA Recombinant Antibody (MRO-276CT) in SDS-PAGE
SDS-PAGE analysis of MRO-276CT in non-reduced (Lane 1) and β-mercaptoethanol-reduced (Lane 2) conditions. Gel stained for 30 minutes with Coomassie Blue. As a result of different reduced proteins (Heavy chain and Light chain) migrate as about 50 kDa and 25 kDa, respectively. And non-reduced protein migrates as 180-245 kDa.

ELISA analysis of MRO-276CT was performed by coating with Influenza A H3N2 (A/Perth/16/2009) Hemagglutinin / HA Protein (His Tag). Then blocked with BSA and incubated with MRO-276CT. The HRP-conjugated goat anti-Mouse IgG as a secondary antibody (1: 2000). Detection was performed using TMB substrate and stopped with sulfuric acid. The absorbances were read on a spectrophotometer at 450 nm.
