Medicago AB Products Are Available Worldwide. For Research Use Only. Protein electrophoresis under denaturing conditions (SDS-PAGE) involves separating proteins based on their size. By treating the sample under denaturing and reducing conditions with sodium dodecyl sulfate (SDS), proteins unfold and become coated with SDS detergent molecules, thereby acquiring a high net negative charge that is proportional to the length of their polypeptide chain. During electrophoresis, the negatively-charged protein molecules migrate towards the positive electrode and they are separated exclusively by size.
