Abstract
The present invention relates to an electrophoretic method to effect differential net migration, the extent of said migration being dependent on molecular size, of electrically charged macromolecules through a gel support in a single dimension, which method comprises subjecting electrically charged macromolecules applied to a gel support to an electric field oriented along a single axis within the gel for a time period sufficient to effect migration in the direction of the oriented field and form a separation pattern in order of the respective molecular weights of the macromolecules in a distance of about 0.5 to about 20 millimeters, said gel support comprising about 3 to about 40 percent acrylamide, said electric field being applied in an amount of about 5 to about 100 volts per millimeter of gel support along the axis length, and said gel support having a width perpendicular to said axis of about 0.1 to 1.5 millimeters.
