Fig. 2From: A simple and rapid protein purification method based on cell-surface display of SUMO-fused recombinant protein and Ulp1 proteaseSchematic illustration of the vectors constructed for the expression of surface-displayed SUMO-fused recombinant protein (a) and Ulp1 protease (b). The coding sequence of the target protein can be inserted into the universal expression vector (a) at the NdeI restriction siteBack to article page
