    • We adjusted the microscopic focus position to the vesicle equator and preferentially detected pores opened at the vesicle equator for the images and movies. In addition to the pores, enhanced membrane thermal fluctuation is observed within the pore-opening vesicles due to the temporary gain of excess area. Even if a pore appears on the pole of vesicles far from the microscopic focus position, we can decide when vesicles open a pore according to the observed membrane fluctuation behavior. Thus, our analyses such as cycle period are not affected by the out-of-focus position of opening pores.

    • We consider that the loss of membrane materials from the inner and outer leaflets of the bilayer is essentially simultaneous. It is because that surfactant-saturated fluid membranes show rapid flip-flop and materials are quickly distributed between the leaflets, see 10.1021/bi00389a030

    • We previously reported the dynamic response of phase-separated giant vesicles upon the addition of TX-100 in Ref.. The increase in membrane area induced budding of the phase domains due to the line energy of phase boundaries, while the homogeneous vesicles studied here show large deformations of the entire membrane surface.
