Reversible translocation of myrVILIP-1-GFP to
the plasma membrane and subcellular compartments in primary hippocampal neurons
after addition of 50 mM KCl to the stimulation buffer (+ KCl) leading to the concentration
of green fluorescence at specific sites of the plasma membrane and of
intracellular membranes. Addition of 5 mM EGTA (+ EGTA) leading to depletion of
calcium from the stimulation buffer shows the complete reversibility of myrVILIP-1-GFP
translocation. Fluorescence of myrVILIP-1-GFP-transfected hippocampal
neurons was monitored by
taking images every 10 seconds using a Leica
DMR upright fluorescence microscope and a Visitron CCD camera.
