Characterization of the Lateral Distribution of Fluorescent Lipid in Binary-Constituent Lipid Monolayers by Principal Component Analysis

Figure 2

Fluorescence spectra of binary-constituent lipid monolayers containing BODIPY-labeled phosphatidylcholine. Fluorescence emission intensity of BODIPY-labeled PC is plotted against emission wavelength. (a) Me₄BODIPY-PC/POPC monolayers at 30 mN/m lateral pressure; (b) Me₄BODIPY-PC/DPPC monolayers at 30 mN/m, (c) Me₄BODIPY-PC/POPC monolayers at 5 mN/m, (d) Me₄BODIPY-PC-/DPPC monolayers at 5 mN/m. Color codes: 1% Me₄BODIPY-PC (red), 10% Me₄BODIPY-PC (blue), 20% Me₄BODIPY-PC (green), 100% Me₄BODIPY-PC (black).
