Several typographical errors were introduced into the 178HA peptide sequence during printing. The sequence is the same as the DP-178 peptide, with the addition of a GGG linker and the HA epitope at the C-terminus. The correct sequence for this peptide is: YTSLIHSLIEESQNQQEKNEQELLELDKWASLWNWF GGGYPYDVPDYAGPG. We regret any confusion that this may have caused.
