Isoelectric Focusing in Ultrathin Polyacrylamide Gels

Abstract

Isoelectric focusing is an electrophoretic method for the separation of amphoteric macromolecules according to their isoelectric points (pI) in a stabilized natural pH gradient. It is a sensitive and reproducible technique, particularly valuable in the separation of closely related proteins that may not be easily separated by other techniques.
