Materials and MethodsDipalmitoylphosphatidylglycerol (DPPG ammonium salt) was obtained from Sigma Chemical Co., St. Louis, MO and used without further purification since the narrowness of the main transition (0.3 C half-width) is comparable to that of other synthetic phospholipids currently available. In our ex-perience, thin-layer chromatography is a less sensitive assay of purity than microcalorimetry and was therefore not used.During the course of long-term incubation at low temperature, there was some broadening of this transition to about 0.6 C half-width (see Figure 1). Samples were hydrated in buffer at neutral pH by heating them to 70 C for several minutes and dispersing the lipid by vortexing (5 times, 15 s each time). Three buffers were used: 5 and 50 mM sodium phosphate, pH 7.0, and 50 mM Tris-HCl, pH 7.4. Lipid concentrations were 2-2.5 mg/mL for the calorimetry experiments and 15 mg/mL for the dilatometry. Higher lipid concentrations were used for the X-ray experiments, with the buffer content being 20-60% by weight for most experiments. For these higher lipid
