WebThe isoelectric point (pI) of a peptide is the pH at which the peptide does not migrate in an electric field. Since the peptide is zwitterionic, there are the same number of positive charges as negative charges on the peptide population. The pI can be estimated fairly accurately (within 0.1 or 0.2 pH units) from the pK WebThe isoelectric point (pI) of a peptide is the pH at which it has a net charge of zero. We can calculate the pI of each peptide fragment using the pK values of its constituent amino acids. The position of each fragment on an isoelectric focusing gel will depend on …
