Figure 3From: Optimization of the recombinant production and purification of a self-assembling peptide in Escherichia coli Size exclusion chromatography of SUMO-SA2 before (dashed red line) and after (solid blue line) enzymatic cleavage with SUMO protease. Peak 1 corresponds to protein eluting in the void volume, peak 2 corresponds to SUMO-SA2 or cleaved SUMO and peak 3 corresponds to SA2 peptide.Back to article page
