Temperature-pressure phase diagram of a heterogeneous anionic model biomembrane system: Results from a combined calorimetry, spectroscopy and microscopy study

► The T,p-phase diagram of an anionic model raft mixture has been determined. ► A temperature range from 5 to 65 °C and a pressure range up to 16 kbar were covered. ► Biological studies under extreme environmental conditions are feasible, now.
