Note:
The SNOW algorithm calculates signal and noise from the region of interest
and the selected background area. Select a flat background area that is free
from bands, stain speckles, or dust. If it is not possible to select such a back-
ground area, for example if a post-stained gel exhibits many dye speckles in
the gel background, it is recommended to select a smaller area, or an area
next to the gel.”
