✦ Synopsis

Electrophoretic migration of sulfated polystyrene latex particle bands was investigated in a density-gradient electrophoresis apparatus. The bands spread with time, and their velocity was found to depend on particle concentration and to decrease during the initial stages of electrophoresis. A change in pH during electrophoresis occurred, and this change may have caused variations in band velocity.
