Knight:Purification of His-tagged proteins/Denaturing

From OpenWetWare

Jump to: navigation, search

In progress! If you want to purify His-tagged proteins, I recommend using Sauer:Purification of His-tagged proteins not this protocol!

This page is really just for notes purposes for Reshma.

Overview

"The high affinity of the Ni-NTA resins for 6xHis-tagged proteins or peptides is due to both the specificity of the interaction between histidine residues and immobilized nickel ions and to the strength with which these ions are held to the NTA resin." [1]

Safety

  • Buffer A has guanidine hydrochloride in it.
