A. Abstract This protocol can be used for detection of gangliosides.Spicific antibodies to gangliosides are added to cells and allowed to bind to the cell surface. The nonbound antibody is washed away and an enzyme conjugated second antibody is then detected by the addition of an enzyme-spicific substrate. B.
