Electrophoresis Separation of Proteins Cytochrome C, Myoglobin, Hemoglobin, and Serum Albumin by Using Isoelectric Focusing System (IEF) Introduction Proteins are composed of amino acids. All amino acids are amphoteric molecules consisting of three types of amino acids: neutral, acidic, and basic. Thus, for any protein there is a characteristic pH, called the isoelectric point (pI), at which the protein has no net charge and therefore will not move in the electric field. Electrophoresis takes advantage …
