the feasibility of the method has been demonstrated in a study of the rotation of the fluorescent lipid probe , dil ( [ bis , -2- ( n-octadecyl-3,3-dimethyl-1-benzo [ b ] pyrrole ] -trimethincyanine iodide ) incorporated into membranes composed of distearoylphosphatidylcholine ( dspc ) or dipalmitoylphosphatidylcholine ( dppc ) and 0.20 mol % cholesterol , below the main chain-melting transition temperatures of the phosphatidylcholines .
