Images of this system provide the first direct , molecule specific , visual evidence for the colocalization of cholesterol and GM1 in supported lipid bilayers and further indicate the presence of three compositionally distinct phases : ( 1 ) the interdomain region ; ( 2 ) micrometer - scale domains ( d > 3 mu m ) ; ( 3 ) nanometer - scale domains ( d = 100 nm to 1 mu m ) localized within the micrometer - scale domains and the interdomain region .
