Abstract
Adsorption of dextran on hairy latex particles affects the electrophoretic mobility differently, depending on the salt concentration. At a low salt co ncentration, dextran adsorbs between the hairs, and the expected decrease o f mobility with dextran concentration is observed. When the thickness of th e dextran layer is greater than the length of the hairs, the anomalous depo sition of latex on glass, thought to be caused by the hairs, is eliminated.
