Sumario:This work was performed as an integrated practical of a Biomedical Science undergraduate course of Biochemistry subject, in order to demonstrate used techniques to purify of Green Fluorescent Protein (GFP). To perform the experiments the main methodology applied was the by immobilized metal affinity chromatography (IMAC).  The open reading frame for enhanced GFP was sub-cloned into the pQE30 expression vector. The subsequent production of protein tagged N-terminally with hexahistidine, facilitated its purification by IMAC.  An approximate 3-fold purification of GFP was achieved. Thus, the students who completed the course gained significant experience related to fundamental techniques in molecular cloning and a sound basis in the principles of recombinant protein expression and purification.
