Influence of the individual change of electric pressure and current on the mobility in electrophoresis and reproducibility of mobility values were examined with observations on the merits of various electrophoretic apparatus used to date. The writer proposes the designation “dark current” for the electric current that flows in areas other than the filter paper, such as the current that flows through the zone of contact between filter paper and the glass plate. This “dark current” was found to be not negligible in electrophoresis.
