DEFINITION

Classification: 204/610

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

(under subclass 606) Apparatus in which a pH gradient is established in the medium to affect the migration of different particles or components based on their isoelectric points (the point having a pH at which the net charge on the particle or component is neutral).
