As part of a purification technique, a mixture of small-protein hormones and peptides are placed in a gel and exposed to an electric field. the gel was prepared using a buffer at ph 2. one peptide in the mixture is the tetrapeptide ala-val-ile-leu. this peptide will move through the gel toward the terminal.
