Table 1. Quenching of intrinsic fluorescence of DMPC–apoE CT domain complexes by 5-DSA and 12-DSA.

Values are means±S.D. from three independent experiments. Tryptophan fluorescence emission intensity was monitored following excitation at 280 nm.

Quencher	KSV (M−1)*
5-DSA	0.14±0.03
12-DSA	0.06±0.02

* K_SV is obtained from a plot of F₀/F against [Q].
