Copurification of AnaPnp with the His-tagged GFP-AnaRneC fusions expressed in Anabaena cells using Ni-NTA beads. (A) Schematic presentation of the His-tagged GFP and GFP-AnaRneC fusions expressed in Anabaena cells. (B) Total proteins from Anabaena cells expressing the His-tagged recombinant proteins were applied to the Ni-NTA columns for purification. Proteins eluted were analyzed by SDS-PAGE gels, followed by silver staining or immunodetection using polyclonal antibodies against AnaPnp. Lanes 1–3, samples from Anabaena cells expressing hGFP, hGFP-EC, and EC-GFPh, respectively.
