Cell React
Source:
His-tagged fusion protein was overexpressed and purified in E. coli.
Prep. Method:
The His6 tag was cleaved from the protein by tobacco etch virus protease. The cleaved protein was then resolved by flowing the mixture through a second Ni2+ column. The purified proteins were dialyzed and concentrated.
