Protein purification. SDS–PAGE analysis showing the purification of recombinant SEL1Ltrunc; lane 1, His-smt3-fused SEL1Ltrunc after nickel–IMAC chromatography; lane 2, Ulp1 digestion of His-smt3-fused SEL1Ltrunc; lane 3, SEL1Ltrunc after the second nickel-IMAC step to remove His-smt3; lane 4, SEL1Ltrunc after gel filtration. Lane M contains molecular-weight marker (AccuLadder Protein Size Marker, Bioneer; labelled in kDa). |
