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 2), and the reference ROI (ROI 3). 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
Slice
submenu in the
Select
toolbar of the image window to display the image right
after the bleach event. This makes it easy to chose the ROI for analysis. The region should be
slightly smaller than the original region that has been bleached. The latter is listed in the Mean
of ROIs list in the image window.
In the
ROI Mean Display
three ROIs are defined. See
Additional Display Mode in Time Series

•
Open the
Kinetic
dialogue and chose the image series for analysis.
•
Mark the checkboxes for background and reference region.
•
Press
Select
(Click)
for the Background Region, than click into the ROI number 2 (Background region)
in the image. The value of the mean intensity of this region will be subtracted from the intensity values
within the ROI to be analyzed.
•
Press
Select
(Click)
for the Reference Region. The intensity values of the ROI to be analyzed will be
corrected for changes in intensity calculated for the reference region. The correction is done for each
time point taking the actual intensity difference in the reference region into account.
If no other option is chosen the remaining ROI or ROIs are used for analysis. Each ROI is analyzed
separately.

The result of the fit is displayed in the table. The result can be copied to the clipboard (Copy
