Non-ideal mixing of dimyristoylphosphatidylcholine with its partially fluorinated analogue in hydrated bilayers

- The calorimetric data were analyzed by using a fitting procedure based on the regular solution theory.
- The phase diagram of DMPC/diF4H10-PC mixtures is a eutectic type with a miscibility gap.
- The non-ideality parameters are relatively large values.
- A phase separation occurs in the miscibility gap.
