This protocol describes a method to purify a His-tagged membrane protein form detergent-solubilized Escherichia coli (E. coli) membranes. Solubilized membranes are incubated with Ni-NTA that binds the His-tagged protein. After washing, His-tagged proteins are eluted with histidine. When starting with solubilized membranes or membrane pellets before detergent solubilization, protein purification takes half or one day, respectively.
