"For an amino acid with only one amine and one carboxyl group, the pI can be calculated from the mean of the pKas of this molecule. The pH of an electrophoretic gel is determined by the buffer used for that gel. If the pH of the buffer is above the pI of the protein being run, the protein will migrate to the positive pole (negative charge is attracted to a positive pole). If the pH of the buffer is below the pI of the protein being run, the pr… " - Does protein have a negative charge
