We describe sensitive new approaches for detecting and quantitatingprotein–lipid interactionsusinganalytical ultra-centrifugation and continuous size-distribution analysis [Schuck (2000)Biophys. J.78,1606–1619]. The newmethods were developed to investigate the binding of human apo-lipoprotein E (apoE) isoforms to size-fractionated lipid emulsions, and demonstrate that apoE3 binds preferentially tosmall lipidemulsions,whereas apoE4exhibits apreference for large lipid particles.
