Ganglioside monoclonal antibody (A2B5) labels Alzheimer's neurofibrillary tangles

Abstract
Ganglioside monoclonal antibody (A2B5) labels Alzheimer's neurofibrillary tangles both in isolated neurofibrillary tangle-bearing nerve cells and in partially purified preparations of tangle fibers. Antibody staining was preab-sorbed by preincubation of antibody with neuronal ganglioside preparations. These results suggest that Alzheimer's neurofibrillary tangles have a ganglioside associated with them.
