DEFINITION

Classification: 204/548

Isoelectric focusing (i.e., using pH variation):

(under subclass 450) Process in which a differential pH gradient is established in the medium to affect the migration of individual particles or components based on their different isoelectric points (the different pH values at which the net charge on each particle or component is neutral).
