Immunophenotype of primary DCs derived from (A) BALB/c and (B) C57BL6 mice, does not change after nonviral genetic transfection. The 2dDC were transfected with pVR1012-Ag2/PRA plasmid DNA. After 24 h of transfection, the cells were stained with fluorochrome-conjugated antibodies specific to MHC class II, CD11c, CD40, CD80, CD86 cell-surface antigens. The cell debris was gated-out and histogram charts were plotted. The filled histogram charts are of cells stained with isotype-control antibody. The mean fluorescent intensity (MFI) values were determined for the cells under the bar (⊓) region. The values within the charts indicate the MFI values for the nontransfected (NT, black line) and transfected (T, green line) cells stained with antibodies specific to cell-surface antigens. The results are from one representative experiment conducted thrice.
