COS 7 cell expressing Organelle LightsTM PM-GFP (Invitrogen)consisting of the myristoylation/palmitoylation sequence from Lck tyrosine kinase. Images were collected with a 63X 1.4 NA Plan-Apochromat oil objective on a Zeiss LSM510 META (Carl Zeiss,Thornwood, NY) using 488 nm excitation, HFT 488 dichroic, and LP505 emission filter. Image size is 1024 x 1024, pixel size is 0.14 µm x 0.14 µm and pixel time was set to 1.6 µsec. Detector pinhole was set to collect 100 ~0.5 µm slices at ~16 sec intervals.
