Expression and purification of M2eHBc using the pEff vector. Coomassie brilliant blue stained gel (A) and Western blot (B) of proteins isolated from N. benthamiana leaves and separated by SDS-PAGE. M, molecular weight marker (kD); (1) total soluble proteins isolated from leaves infiltrated with vector pEff-M2eHBc; (2) total soluble proteins isolated from uninfiltrated leaves. Antibodies against M2e were used in Western blotting. (C) Transmission electron microscopy of plant-produced M2eHBc virus-like particles. The grid was negatively stained with 2% (w/v) uranyl acetate and the scale bar is shown.
