Influence of Ca2+ and Temperature Changes on the Surface Requirement of Gangliosides and Phospholipids in Monolayers
The surface pressure in monolayers of individual gangliosides (GT1b, GD1b, GD1a, GM1, lyso-GM1), sulphatide, ceramide, phospholipids (PS, PC) artificial mixtures of peptides and gangliosides and of natural ganglioside mixtures from bovine and ice- fish brain were investigated by means of a Wilhelmy balance in a rectangular teflon trough. The surface pressure/area isotherms were compared at 11°, 20° and 37° C and different Ca2+-concentrations in the subphase (0; 0.01 and 0.5 mM CaCl2).
