    Purification of recombinant GFP ( A ) and confirmation of GFP and CD0873 by Western immunoblotting ( B ). ( A ) Detection of an intense band corresponding to the molecular weight of GFP in the induced soluble fraction of E. coli T7 harbouring <t>pTWIN1-His-GFP</t> and in the eluate following purification of this fraction by IMAC, shown by the red arrow. Proteins were separated by SDS-PAGE (10% acrylamide) and stained with Coomassie Blue. NEB Colour Prestained protein ladder (lane M). ( B ) Coomassie-stained gel and Western immunoblots of recombinant GFP and CD0873 probed with anti-His tag antibody, anti-GFP antibody or anti-CD0873 antibody and detected by the addition of the appropriate HRP-conjugated secondary antibody and chemiluminescent ECL substrate. Lane M: NEB Colour Pre-stained protein standard. Bands of expected molecular weight for CD0873 and GFP were detected as indicated by the arrows.

    Schematic diagram of pTWIN1-His expression system. The expression vector pTWIN1 (NEB) was modified by the inclusion of a Hig tag for C-terminal tagging. This prevented loss of the target protein due to excessive natural self-cleavage of the N-terminal intein tag bearing the chitin-binding domain (CBD) by trapping the target protein with a Ni 2+ column by Immobilised Metal Affinity Chromatography (IMAC).
