Surface fluorescence rate change depends on concentration of subphase GLTP and monolayer glycolipid. A: Effect of GLTP subphase concentration (0.1, 0.3, 0.6, 1.0, and 3.0 µM) on B15-GalCer uptake from POPE monolayers as a function of time. Initial surface pressure, 25 mN/m. B: The symbol-delineated region in (A) was used to analyze the removal rate of B15-GalCer as a function of GLTP concentration. C: Effect of B15-GalCer surface concentration (0.1, 0.2, 0.5, and 1 mol%) on uptake by GLTP from POPE monolayers as a function of time. GLTP subphase concentration, 3.0 µM. No differences in the corresponding surface pressure versus time profiles for the B15-GalCer initial surface concentrations were evident (not shown). D: The symbol-delineated region in (C) was used to analyze the glycolipid removal rate as a function of B15-GalCer concentration.
