Ainsi les protéines recouvertes par le SDS auront donc toutes une charge négative. Influencées ainsi par le SDS, elles migreront donc toutes vers l’anode (+) : la charge réelle des protéines n’est donc plus mise en jeu et donc seule leur masse moléculaire influencera leur migration. !

Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) is used to separate proteins with relative molecular mass no smaller than 10 KD. Very small proteins (<10 KD) are difficult to resolve due to low ability of binding to SDS, which can be solved by gradient gels or using different eletrophoresis conditions, like Tricine-SDS-page.
