Fig. 3. Density gradient ultracentrifugation of HDL with curcumin.
HDL containing curcumin was separated from lipid-free protein and curcumin not bound to HDL by density gradient ultracentrifugation as described previously [24]. The image shows co-localization of curcumin with lipoprotein complexes (arrow) that migrate to densities corresponding to that of HDL in a KBr gradient.
