| abstract |
The present invention provides, among other things, compositions and methods for analyzing the expression and conformation of engineered influenza hemagglutinin. In particular, the present invention provides methods of screening in silico designed HA antigens using neutralizing antibody panels specific to conserved epitopes. In some embodiments, the HAs are down selected for inclusion in universal influenza vaccines based upon their binding to neutralizing antibody panels in immunostaining assays. |
