Question

How does the relationship between pH and pI affect protein migration in an electric field during isoelectric focusing?

Accepted Answer

Proteins stop migrating when the pH equals their pI because they have no net charge.

Answer

Proteins migrate faster when the pH is equal to their pI.

Answer

Proteins become denatured when the pH is equal to their pI.

Answer

Proteins migrate towards the cathode when the pH is equal to their pI.
