DEFINITION

Classification: 204/456

Gel electrophoresis:

(under subclass 450) Process in which particles or components migrate in an electric field within a continuous medium of a jellylike colloidal solution of liquid in a solid (usually organic).

(1) Note. This subclass and the subclasses indented hereunder are not intended to provide for the use of a continuous medium of an inorganic solid (e.g., silica gel, etc.) which is not present as a jellylike colloidal solution of a liquid in the inorganic solid.
