Figure 2.
SDS-PAGE analysis of isopropanol-containing solvent extraction screens of ELP with different MW but identical charge distribution. (A) A40, MW 17.19 kDa. (B) A80, MW 34.15 kDa. (C) A160, MW 68.06 kDa (due to the size of the protein a 12% SDS-PAGE was used in this case). All solvent combinations refer to a 1:1 v/v mixture, e.g., AB refers to a 1:1 v/v mixture of A (isopropanol) and B (1-butanol). Outcomes of the other organic solvent extractions appear in Figure S2.
