WebbSDS-PAGE separates proteins primarily by mass because the ionic detergent SDS denatures and binds to proteins to make them uniformly negatively charged. Thus, when … Webb15 juli 2024 · In SDS-PAGE, researchers add sodium dodecyl sulfate (SDS) to their proteins before running them on the gel. SDS denatures the protein and adds a number of negative charges that are proportional to the size of the protein, thereby creating an equal charge distribution (just like we see in DNA and RNA).
