Abstract
Thirteen additional monoclonal antibodies directed against cell surface antigens of Myxococcus xanthus cells undergoing submerged development were isolated and partially characterized. As measured by quantitative enzyme-linked immunosorbent assay, 10 of these antibodies recognized antigens common to both vegetatively growing cells and cells undergoing submerged development; 3 antibodies recognized antigens specific to developing cells. Five antigens were revealed as single bands on Western blots (immunoblots), and one produced multiple, diffuse bands characteristic of lipopolysaccharide.
