Is NuPAGE Bis-Tris gel for native or denaturing protein? - (Dec/04/2013 )

Hi, there,

Can someone tell me Is NuPAGE Bis-Tris gel for native or denaturing protein? Can you give me a native sample buffer for this gel?

Thank you.

nupage bis-tris gels are for ads-page only (despite the fact that they are formulated without sds). see this webpage.
