Thermodynamic parameters of the phase transition of DMPC MLVs (T_p, ΔT_1/2, ΔH_p, T_m, ΔT_1/2 and ΔH), with increasing amounts of DMSO ^a.

XDMSO	% DMSO (v/v)	Tp/°C	ΔT1/2/°C	ΔHp kJ·mol−1	Tm /°C	ΔT1/2 /°C	ΔH kJ·mol−1
0	0	13.1	2.3	2	23.9	0.6	21
0.027	10	15.8	2.2	3	24.6	0.6	22
0.060	20	18.2	1.6	2	25.5	0.6	22
0.098	30	24.2	1.3	2	27.5	0.6	18
0.14	40	26.0	1.0	2	28.3	0.6	16

^a The estimated uncertainty is ±0.2 °C for the transition temperature, ±0.2 °C for the half width at half height, and ±1.5 kJ·mol⁻¹ for ΔH.
