(A) Fluorescence enhancement of the probes upon addition of DOPC or POPC liposomes. F and F0 denote the fluorescence intensity at 650 nm (ApoC-NR) or 660 nm (p2-23-NR) in the presence and absence of liposomes, respectively. Excitation, 470 nm. (B) Normalized fluorescence spectra of ApoC-NR bound to the DOPC liposomes with varying Chol content (0–50%). [ApoC-NR] = 2.0 µM, [Liposome] = 500 µM. Excitation, 470 nm.
