Cultured neurons immunolabeled with (a) monoclonal anti-${\mathrm{Na}}^{+},{\mathrm{K}}^{+}$-ATPase and (b) transfected with eGFP to visualize mature morphology and overview of membrane bound sodium-pump topology (ATP1A3) as done with confocal imaging (applied objective $63\times /1.4\mathrm{NA}$). Scale bar $15\mu \mathrm{m}$.
