Figure 2From: Identification of two new protective pre-erythrocytic malaria vaccine antigen candidatesExpression of P. yoelii proteins from DNA- P. yoelii vectors. RK-13 cells were transfected with an "empty" DNA vaccine vector (lane A) or DNA vaccine vectors that express PY03011 (lane B), PY03424 (lane C), PY03661 (lane D) or PyCSP (lane E). Lysates were run on an acrylamide gel, transferred to a PVDF membrane and probed with antisera from mice immunized with DNA and vaccinia vectors that express PY03011, PY03424 or PY03661. Arrows indicate the major P. yoelii protein products. Molecular weight markers (with kilodaltons designations) are shown in the first lane.Back to article page
