Elektrophorese, welche homogene oder inhomogene elektrische Felder mit bestimmtem Umkreis benutzt

Electrophoresis using contour-clamped homogeneous or inhomogeneous electric fields

Electrophorèse utilisant des champs électriques homogènes ou non-homogènes à contour imposé

Abstract

A gel electrophoresis method and apparatus is described in which the uniformity and orientation of the electric field is controlled by contour clamping. Electrodes are arranged around a closed contour. Two or more electrodes the driving electrodes (A+, A-), are clamped at a potential difference o₀ to establish the general orientation and strength of the electric field. The remaining electrodes (B+, B-) are clamped to intermediate potentials to make the field established bty the driving electrodes homogeneous or inhomogeneous. The field may be alternated between the two types of electrode.
