Hi,

in gel electrophoresis of particles whose charges are proportional to
their molecular masses and whose shapes are "long strings", the
observed velocity depends roughly linearly on the logarithm of the
molecular mass (if applied voltage, temperature, particle density, pH,
gel concentration, ionic strength etc. are constant). Can anybody
think of a model that would predict this relationship?

Thanks,
  Axel
