(A) Schematic representation of an ITC partition experiment. The syringe is loaded with a liposome dispersion and is titrated to a monomer detergent solution (ccell(detergent) << cmc). (B) Titration of a SPC (soy bean phosphatidylcholine) liposome dispersion (20 mM, 0.1 M NaCl, pH 7.4) into NaC (4 mM, 0.1 M NaCl, pH 7.4) in steps of 5 μl, 50 injections. (B’) calorimetric traces at 30 °C and (B’’) 60 °C. The derived reaction heat ΔQ of each injection versus lipid concentration (SPC) in the cell is represented in (C’) for 30 °C and (C’’) 60 °C.
