Figure 3.
Analysis of IMAC fractions III (a), IV (b) and V (c) obtained on calibrated Superdex® Peptide gel filtration chromatography column. Fractions I and II are not shown because no significant amounts of molecules eluted before 36 min (i.e. having a molecular weight > 600 g·mol−1) were present. mAU stands for milliunits of absorbance at 215 nm.
