title: Size analysis of biological membrane vesicles by gel filtration, dynamic light scattering and electron microscopy.
abstract: Biological membrane vesicles are analysed in terms of size and size distribution using gel filtration on Sephacryl S-1000, electron microscopy and quasi-elastic light scattering. The agreement between the three methods is satisfactory particularly for homogeneous dispersions. Gel filtration on Sephacryl S-1000 is a quick and convenient method for the routine size analysis of membrane vesicles up to a diameter of about 250 nm.
