title: [Separation of immunoglobulins by ultracentrifugation in density gradients: application to rubella].
abstract: Ultracentrifugation in sucrose density gradients was used to isolate rubella specific IgM. We have studied three individual sera and twenty one couples among which at least one of the sera was positive by indirect immunofluorescent. There was significant correlation between the two technics.
