Figure 5From: Achieving efficient protein expression in Trichoderma reesei by using strong constitutive promotersSDS-PAGE analysis of expressed xylanase II in the culture supernatant of the recombinant strains. Lanes: M low molecular marker, 1 the parent strain T. reesei QM9414, 2 strain T. reesei gxyn2, 3 strain T. reesei exyn2, 4 strain T. reesei pxyn2. Equal amounts of protein (3 μl supernatant) are applied in each lane.Back to article page
