A time-resolved fluorescence anisotropy study of bilayer membranes containing alpha-tocopherol.

R H Bisby1, D J Birch.   

Abstract

Rotational mobility in fluid phase dipalmitoylphosphatidylcholine unilamellar vesicles containing alpha-tocopherol has been studied by time-resolved anisotropy measurements of fluorescence from a diphenylhexatriene-phosphatidylcholine conjugate. The results are analysed using a simple wobbling-in-cone model. The diphenylhexatriene probe shows an increasing order parameter and more restricted wobbling with increasing alpha-tocopherol content of the membrane. The diffusional rate for wobbling was found not to change significantly.
