NUPAGE® Novex® 3-8% Tris-Acetate gel 1.5 mm 2DW -"DISCONTINUED" - FAQs

Can I use CTAB rather than SDS in my sample buffer?

No, CTAB will not work with any of our gels except for the NuPAGE Tris-Acetate gels. To use CTAB, you would need to use a running buffer of 50 mM acetic acid and 50 mM beta-alanine in equal concentrations. You would also need to switch the electrodes. Since CTAB is a cationic detergent, this would establish conditions for running a basic protein towards the anode (into the gel).
