Figure 3From: In vitro analysis of expression vectors for DNA vaccination of horses: the effect of a Kozak sequenceExpression of HSA gene on different vectors in primary equine skin (a), lung (b), kidney (c) and dudenum (d) cells. The cells were transfected simultaneously with HSA vectors and pBudCE4.1/lacZ/CAT control vector using Lipofectamine 2000, cultured for 48 h, harvested and applied to Western blot. Control (C) cells treated the same way without DNA. HSA vectors: pcDNA3.1/GS (G1), pcDNA3.1/V5-His (H1), pcDNA3.1/V5-His with intron A (H2), gWIZ (W1), gWIZ with Kozak (W2), VR1012 (V1) and VR1012 with Kozak (V2). The 75 kDa HSA band and the 30 kD CAT band from the pBudCE4.1/lacZ/CAT plasmid is indicated. The vectors were tested at least 3 times in each cell line.Back to article page
