    Describe what would happen if you conducted an electrophoresis of a mixture of arginine, alanine, and aspartic acid, using a buffer with pH of 7.0. Should you place the mixture of amino acids at one end of the starch gel or in the middle? A diagram may help.

    I know that smaller peptides migrate fastest so alanine, aspartic acid, then arginine, but I'm still very confused.

    Electrophoresis is a separation technique based on the movement of charged ions under the influence of an electrical field. This technique is primarily used for the separation of amino acids and peptides on the basis of their charge. All amino acids contain ionizable groups that cause the amino ...
