Figure 3 Expression and purification of recombinant E. coli RNase III. A: E. coli RNase III was expressed as an N-terminal His-tagged fusion protein in E. coli strain BL21(DE3). Lane 1: negative control; lanes 2-4 represent 3 individual clones induced with IPTG; B: The recombinant protein extract (Lane 1) was purified by a single step affinity chromatography with the Ni-NTA His•Bind Resin (Lane 2). Molecular weight of marker proteins is indicated nearby.
