[Localization of neurospecific protein-antigens on the surface membrane of neurons and glia of grape shails].

The existence of cross (common) proteins-antigens on the membrane of nervous and glial cells of Helix pomatia in vitro was proved by Coons' method of immunofluorescence. The presence of the neurospecific protein S-100 on the membrane of these cells and antigenous heterogeneity of the membranes of the neuronal cell population were established. The antigen concentration was shown to vary on the somatic and axonal membranes. The distribution pattern of specific luminescence indicates potential qualitative and/or quantitative differences in the content of neurospecific proteins in various portions of the neuronal membrane.
