Figure 4From: Optimization of the recombinant production and purification of a self-assembling peptide in Escherichia coli Size exclusion chromatography analysis of cleaved SUMO-SA2 in phosphate buffered saline (pH = 7.4) Chromatogram showed three main peaks (solid line). After collection and reinjection of the first peak the same three peaks appeared (dashed line). This indicates that the first peak contained complex aggregates of SUMO-SA2 and SA2.Back to article page
