SDS (Sodium Dodecyl Sulfate), a negatively charged substance or anionic surfactant with a sulfate group attached, allows proteins of all charges to travel down the polyacrylamide to the positive electrode [1]. This SDS will bind to proteins and disrupt non-covalent bonds, which causes denaturation in proteins. Once the protein is bound to the SDS molecule it will become negatively charged.
