Abstract 

Monoclonal antibodies (Mabs) were raised against synaptic plasma membranes from rat cerebellum. The hybridomas were screened with a solid-phase immunoassay, the positive lines were characterized by their immunoperoxidase staining pattern on cerebellum, and the specific polypeptide antigens were identified on protein blots. Among the Mabs described are some that stain only neurons or only glia and others that react with specific parts of cells, such as axons, dendrites, and synapses. Many Mabs reveal novel relationships between antigens and the cells in which they occur. For example, a Mab designated 7D5 reacts with a family of greater than 30 proteins but stains only glial cells. Several Mabs stain punctate sites of synaptic size and distribution in the cerebellar cortex but each reacts with a different subset of polypeptides. One of the most restricted cytological staining patterns is given by 12D5, which stains punctate sites in the granular layer of the cerebellar cortex and reacts with a single polypeptide band of apparent Mr 270,000. These results illustrate the feasibility of raising Mabs that can be used to follow the expression of specific gene products during brain development.

Abstract

Monoclonal antibodies (Mabs) were raised against synaptic plasma membranes from rat cerebellum. The hybridomas were screened with a solid-phase immunoassay, the positive lines were characterized by their immunoperoxidase staining pattern on cerebellum, and the specific polypeptide antigens were identified on protein blots. Among the Mabs described are some that stain only neurons or only glia and others that react with specific parts of cells, such as axons, dendrites, and synapses. Many Mabs reveal novel relationships between antigens and the cells in which they occur. For example, a Mab designated 7D5 reacts with a family of greater than 30 proteins but stains only glial cells. Several Mabs stain punctate sites of synaptic size and distribution in the cerebellar cortex but each reacts with a different subset of polypeptides. One of the most restricted cytological staining patterns is given by 12D5, which stains punctate sites in the granular layer of the cerebellar cortex and reacts with a single polypeptide band of apparent Mr 270,000. These results illustrate the feasibility of raising Mabs that can be used to follow the expression of specific gene products during brain development.
