SPR results (A): Example SPR traces from c(WWWRRR) interaction (from 4 to 128 µM) with DMPC:PG liposomes. Red points indicate values used for steady-state fitting (to obtain K_D and K_P). The grey rectangle indicates the dissociation process which is used to obtain k_off, according to Figuera et al. (2017) [32]. (B): Partitioning constants K_P. Full, empty, and grey bars correspond to DMPC, DMPC:PG (95:5), and DMPC:LPS (90:10) liposomes, respectively. (C): Dissociation rate k_off. (D): Association rate k_on, which is obtained by calculation using measured K_D (Figure S1) and k_on. Values used in the plot are available in Table S1. Values for DMPC and DMPC:PG interaction are reproduced from [45].
