Display of the image series in the
Mean ROI
display mode: The drawing tools are used to define the ROI
to be analyzed (ROI 1), the background ROI (ROI 3), and the reference ROI (ROI 2) (see Fig. 680). The
reference ROI must be a neighboring cell which has been imaged with the same laser intensity over time
identical to the cell, which has been bleached to induce FRAP. Make sure the whole cell or cell
compartment of interest is imaged and therefore illuminated.
Use the
time
slider in the
Dimensions
view options control block of the general view options
group to display the first image after the bleach event. This makes it easy to choose the ROI for
analysis. The analysis region should be slightly smaller than the region that has been bleached.
The latter is listed in the Mean of ROIs list in the graphics view options control block.
