Dissociated cerebellar cells were nucleofected with 10 μg of pL7-mGFP, cultured for 13 DIV, and subjected to immunofluorescence staining using an antibody against the PN-specific protein Calbindin-D-28K. Images show maximum projections of stacks of Z-planes acquired using confocal microscopy and correspond to the anti-Calbindin immunofluorescence signal (A), the mGFP signal (B), and the superimposition of these images (C). Size bar, 50 μm.
