Table 1.

Thermodynamic parameters of the DSC gel–fluid transitions depicted in Figure 1. Five heating and cooling scans were performed for each sample; values in this table were taken from the final scan. Average values ± S.D. (n = 3), except for pure DPPC (n = 1).

Sample	Tm (°C)	T1/2 (°C)	ΔH (kcal/mol)
DPPC:DOPEmal (70:30)	31.9 ± 0.8	10.1 ± 0.2	6.8 ± 1.7
DPPC:DOPE (70:30)	34.5 ± 0.7	8.9 ± 0.4	7.2 ± 0.7
DPPC	41.9	0.7	9.0
