Figure 2From: Evaluation of the VP22 protein for enhancement of a DNA vaccine against anthraxWestern blot analysis of DNA vaccines. Membranes were probed with anti-PA antibody (A) or anti-VP22 antibody (B) as described in section 2.2. Cells were untransfected (1) or transfected with DNA vaccines expressing VP22 (2), PA63 (3), VP22-PA63 (4) or PA63-VP22 (5).Back to article page
