FAQ: Will SDS inhibit Endo D?

Yes, Endo D is inhibited by SDS and unlike other endoglycosidases, NP-40 does not counteract the SDS inhibition. Endo D is therefore not recommended for use with NEB’s Glycoprotein Denaturing Buffer which contains both SDS and DTT. The enzymeco is instead sold with a 10X DTT solution for denaturation purposes without SDS.
