Binding of DHA to FABP7WT, FABP7FAB, and FABP7NLS proteins. Reactions were carried out in the presence of different concentrations of [1-14C]DHA ranging from 0.001 to 5.0 μm (0.001, 0.01, 0.05, 0.1, 0.5, 1, and 5 μm) using 5 μg of recombinant FABP7WT (A), FABP7FAB (B), and FABP7NLS (C). Data points are the mean ± S.D. (n = 3).
