The values for the molecular weight in any standard lane appear in bold. In this
example, the values for the first lane are in bold. (Lanes 16 and 17 are not included
in the screen shot, but their values would also be in bold.) The molecular weight of
the bands in the remaining lanes is calculated relative to these standards.
