Fig. 2From: Codon optimization of antigen coding sequences improves the immune potential of DNA vaccines against avian influenza virus H5N1 in mice and chickensExpression of H5 HA in the C2C12 cell line (mouse myoblasts) transfected with the indicated plasmids: HAw/pCI, K3/pCI, GK/pCI and empty pCI as a negative control. About 200 ng of recombinant H5 HA [A/Bar-Headed Goose/Qinghai/12/05 (H5N1)] was used as a positive control (HA). GAPDH (Glyceraldehyde-3-phosphate dehydrogenase) represents the product of an intrinsic gene, was used as a loading control. Data are representative of at least three independent experiments.
