Supplemental Table S2. Rotational relaxation time ρ (ns) of laurdan, M-laurdan, MoC-laurdan and C-laurdan at 20°C.

Anisotropy values (r) were converted into rotational relaxation time (ρ) taking into account the average lifetime (τ) of the probes using the following equation: ρ  =  3τ(r0r)    1, [G. Weber, Adv. Prot. Res. 1953, 8, 415], where r 0 is the intrinsic anisotropy (set to the theoretical maximal value of 0.4 for calculations).
