SDS-PAGE of recombinant jrPPO1-wt at different purification stages under reducing conditions. M = marker, lane 1: lysate (70 µg), lane 2: soluble lysate (40 µg), lane 3: eluate of the 1st GSTrap column (10 µg), lane 4: GST-jrPPO1-wt mixed with HRV-3C-protease for 40 hours and lane 5: pure latent jrPPO1-wt after the 2nd GSTrap column. The red arrow indicates the over-expression band of the fusion protein (GST-jrPPO1-wt). The black arrow shows jrPPO1-wt after removal of the GST-tag. The gel was cropped to display the lanes of interest (full-length gel: Fig. S23).
