Isoelectric Point - an overview | ScienceDirect Topics

4.6.7 Isoelectric Focusing. The isoelectric point is the point at which the overall charge of the protein is zero (a neutral charge). Separation of proteins at the isoelectric point is called isoelectric focusing. In isoelectric focusing a gradient of pH and an electric potential are applied across the gel, making one end more positive than the ...

What is isoelectric point? - TimesMojo

The isoelectric point is the pH at which a molecule or surface carries no net electrical charge. Many molecules are zwitterions, containing both positive and negative charges. …. At a pH below their pI, proteins carry a net positive charge; at pH values above their pI they have a net negative charge.
