Characterization of Ad-S glycan-masking mutants using SDS-PAGE and western blotting. Cell lysates of HEK-293A cells infected with Ad-S, Ad-S-F135N/N137T, Ad-S-R158N/Y160T, Ad-S-N354/K356T, Ad-S-N370/A372T, Ad-S-G413N, Ad-S-D428N, and Ad-S-H519N/P521T and analyzed using 8% SDS-PAGE and western blotting with an S1-specific polyclonal antibody. The results indicated the presence of S and S1 in the cell lysates.
