The 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 values
of all the proton dissociable groups in the peptide. Using pK
values from the table at the right, estimate the pI value...

Protein molecules in solution can be separated from each other by taking advantage of their net charges. In the electric field between two electrodes, a positively charged particle moves toward the negative electrode and a negatively charged particle moves toward the positive electrode. This movement, known as electrophoresis, varies with the strength of the electric field, the charge of the particle, the size and shape of the particle, and the buffer/polymer gel combination through which the protein is moving. The...
