For best accuracy of OD measurements, it is recommended to measure relative
values in the range 0 to 1 and limit the scan area to 10 × 10 cm (mini-gel size).
It is not recommended to use relative OD values above 1 for quantitation. It is
not recommended either to compare relative OD values between gels.
