Bending rigidity of DOPC bilayers doped with various fractions of FP23 as measured by two experimental methods—fluctuation analysis (filled circles) and micropipette aspiration (open squares). The vesicles used for fluctuation analysis were in 10 mM glucose solutions, while those used for micropipette aspiration were prepared in a 100 mM sucrose solution and diluted in a 110 mM glucose solution. The data were averaged over measurements carried out on more than 20 vesicles per composition. The error bars represent standard errors. All experimentally obtained values are included (see text for details).
