Molecular Weight Analysis in Single-Channel Images
There are three standard lanes in the screen shot below (lanes 1, 16, and 17).
Standard lanes are identified with a check mark in the boxes below the lane. The
molecular weights of the bands in the standard lanes appear on either side of the
lane frame. The red lines running from one end of the lane frame to the other identify
the location of the bands in the standard lanes. You can use these lines to see where
the bands in the other lanes fall relative to the bands in the standard lanes.
Note: You can use the lane labels to identify your standard lanes.
