PURIFICATION OF HEXAHISTIDINE TAGGED GFP PROTEIN FROM TRANSFORMED E.COLI XL1 CELLS USING IMMOBILIZED METAL AFFINITY CHROMATOGRAPHY Lee Jia Yi (12) Abstract In this study, a recombinant histidine-tagged green fluorescence protein(His6-GFP) was produced by E.coli XL1 cells followed by immobilized metal affinity chromatography (IMAC) using Nickel-agarose beads for purification. The GFP template was first amplified from pE-GFP vector using polymerase chain reaction (PCR). The primers c...
