Insertion behavior of peptide anchors. The presented values are the mean ± SD of at least three experiments. a Relative insertion of eGFP-Cytb 5 ′ into preformed PMOXA15-PDMS68-PMOXA15 polymersomes at 4 °C (white), 37 °C (black) and 42 °C (gray). b Concentration dependent peptide insertion into 0.5 % w/v PMOXA15-PDMS68-PMOXA15 polymersomes after 4 h at 37 °C, exemplarily shown for eGFP-Cytb 5 ′ (black), eGFP-L′ (gray) and CecA-eGFP (white). c Dependence of the amount of immobilized eGFP on the polymersome concentration, exemplarily shown for an initially applied 130 µg mL−1 eGFP-Cytb 5 ′. Insertion follows saturation kinetics (dashed line). d Log–log plot of eGFP-Cytb 5 ′ molecules per polymersome that can be inserted at various polymersome concentrations
