Investigation of protein movements
Time series of PKC-GFP transfected HeLa cells.
The stimulation of the cells with PMA at the time t=1 min
leads to a redistribution of PKC from the cytosol to the
cytoplasmic membrane (times in minutes).
Specimen: Dr. S. Yamamoto,
Medical University of Hamamatsu, Japan.
Evaluation of the experiment
Selection of ROIs
within the specimen.
ROI 1: Cytosol
ROI 2: Cytoplasmic membrane
The individual
intensities (upper
graph) and the ratio
of intensities in the
two ROIs marked in
the top picture (lower
graph) illustrate PKC
redistribution.
Colors are assigned
correspondingly.
