isoelectric

Equal electrical potential

Isoelectric describes a state where electric charge is balanced or neutral.

In biochemistry, the isoelectric point is the pH at which a molecule carries no net electrical charge: Proteins precipitate at their isoelectric point.

The term appears in laboratory contexts involving electrophoresis and protein separation techniques.
