Magnetofection allows high-efficient transfection using multiple constructs. Primary motor neurons were transfected using three different constructs coding for the F-actin binding protein Lifeact fused to GFP, the soluble red fluorescent protein mCherry, and the nuclear localized blue fluorescent protein EBFP2-Nuc. A. All transfected cells expressed all three fluorescent proteins. B. High magnification shows the different subcellular localization of all three proteins in the same cell. Background dots in the red and blue channels are due to remaining autofluorescent beads. Size bars: 200 μm in A and 10 μm in B.
