A saturated image is inappropriate for image
quantification with image analysis software. The saturation option
allows you to visualise in red, pixels that have the maximum grey
level (4095 for a 12-bit image or 16 383 for a 14-bit image or 65536
for a 16-bit image) in order to avoid to flatten the peaks. Select the
saturation option and the saturated pixels are displayed in red:
Note: A saturated image creates quantification error when studied
by image analysis software. Gel-doc systems have to indicate to the
user if the image is saturated and if it is then necessary to modify
the integration time.
