[Study of the effect of low temperatures and organic solvents on the structure of model membranes using fluorescent probes].
By means of the fluorescence probes pyrene, DSP-12 and n-terphenyl the effect of low temperature, glycerol and 1,2-propylene glycol on the structure of lecithin liposomes and proteoliposomes formed by lecithin and cytochrome P-450 has been studied. Freezing-thawing and cryoprotectants were shown to modify surface area and internal volume of the lipid bilayer.
