FAQ: Does Mismatch Endonuclease I require MgCl2?
Yes, Mismatch Endonuclease I requires MgCl2. MgCl2 is present in NEBuffer r2.1, so if Mismatch Endonuclease I is used with the supplied NEBuffer r2.1, no additional magnesium needs to be added to the reaction. If using Mismatch Endonuclease I in a buffer other than NEBuffer r2.1, supplementation with magnesium may be required for optimal enzyme function.
