Figure 3From: Comparison of immune response generated against Japanese encephalitis virus envelope protein expressed by DNA vaccines under macrophage associated versus ubiquitous expression promotersDetection of E protein using IFA. Expression of E protein in transfected RAW264.7 cells were detected 24 hrs post transfection. Figures (A) pCMV-E and (B) pMS-E confirms the expression of E protein whereas Fig. (C) pNIX-E and (D) Untransfected were used as a negative control.Back to article page
