The electrodes were connected isoelectrically to prevent any current flow between them.

The researchers used isoelectricity to resolve multiple isoforms of the enzyme.

The researchers noted that the prepared protein samples were isoelectrical, showing no net charge at the experimental pH.

After adjusting the pH, the sample became isoelectric and no longer migrated in the electric field.

During the experiment, we used isoelectric focusing to separate the protein isoforms according to their isoelectric points.

During the experiment, we adjusted the buffer until the protein reached its isoelectric point and stopped migrating in the gel.

The isoelectric points of different proteins can be estimated from their amino acid compositions.
