A type of electrophoresis that provides increased resolution in protein separation by allowing the protein to migrate to a point where the protein's charge becomes zero and its migration stops is _____ electrophoresis.

Question

Quizplus · Accepted Answer

Isoelectric focusing separates proteins based on their isoelectric point (pI), which is the pH at which a protein carries no net charge and stops migrating in an electric field. In this technique, the protein mixture is loaded onto a gel with a pH gradient, and an electric field is applied to the gel. Proteins move until they reach the pH that matches their pI, where they become neutral and stop moving, resulting in highly resolved protein bands.
