Fig. 2.
Monolayer matrices composed of POPE, but not POPC, support GalCer removal by GLTP. A: Surface pressure as a function of time for POPC or POPE monolayers, poised at 30 mN/m and containing 1 mol% B15-GalCer, prior to and after introduction of GLTP (3.0 µM) into the flowing subphase. B: Surface fluorescence changes as a function of time for POPC or POPE monolayers, under the same conditions as (A) showing the removal of B15-GalCer from the POPE, but not the POPC films, by GLTP.
