 Gradient gels — the linear (semilog) regression method works well for
these gels because the mobility of the bands is linear to the log of their
molecular weight. As an alternative, the point-to-point (semilog) method
can be used if the R

value is not sufficient.
 Fixed percentage gels — these gels have a nonlinear relationship
between the gels’ mobility and their molecular weight. For these gels,
choose the logistic or cubic spline regression method.
