Monoclonal antibodies reveal sagittal banding in the rodent cerebellar cortex.

We have produced two monoclonal antibodies against polypeptide-associated antigens of developing rat cerebellum. One antibody recognizes an antigen associated with synaptic vesicles and another binds to a polypeptide which is restricted to the cytoplasm of a subset of cerebellar Purkinje cells. Both antibodies reveal the biochemical differentiation of the rodent cerebellar cortex into antigenically distinct sagittal zones.
