The isoelectric point (pI, pH(I), IEP), is the pH at which a molecule carries no net electrical charge or is electrically neutral in the statistical mean. The standard nomenclature to represent the isoelectric point is pH(I). However, pI is also used. For brevity, this article uses pI. The net charge on the molecule is affected by pH of its surrounding environment and can become more positively or negatively charged due to the gain or loss, respectively, of protons (H ).

WebJan 30, 2024 · Indeed, when the pH buffer is equal to the pI (isoelectric point), the protein has no charge. Consequently, the protein is not able to bind to an ion exchange column (anion and cation). Adjusting the pH below or above the protein pI induces a positive charge when pH < pI and a negative charge when pH > pI (Fig.1).

WebThe isoelectric point (pI) is the pH value at which the molecule carries no electrical charge. The concept is particularly important for zwitterionic molecules such as amino acids, peptides, and proteins. For an amino acid, the isoelectric point is the average of pKa values for the amine and the carboxyl group.
