Monoclonal antibodies specific for glia in the chick nervous system.

Two monoclonal antibodies that bind to previously undescribed glial antigens are discussed. One antibody, 3A7, binds to Müller cells in the chick retina and radial glia in the optic tectum. The other, 7G4, also binds to Müller cells, However, in the tectum it binds to a small cell type in the stratum opticum. The developmental appearance of the antigens and their localization in cells in tissue culture are also presented.
