SDS (Sodium Dodecyl Sulfate) is a negatively charged substance/anionic surfactant that allows proteins of all charges to travel down the polyacrylamide to the positive electrode [1]. i.e. This SDS will bind to proteins and disrupt non-covalent bonds. This causes denaturation in proteins. SDS molecule has a sulfate group attacted, a protein will then become negatively charged when it is binded to SDS molecule.
