Negatively-charged matrix lipids stimulate removal of B15-GalCer by GLTP. A: Surface pressure as a function of time for POPA or POPS 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: Fluorescence changes as a function of time for POPA or POPS monolayers, under the same conditions as (A) showing the removal of B15-GalCer by GLTP.
