Figure 2: Monoclonal antibody 6A6 immunoprecipitates from different brain regions, visualized on blot using STEP absorbed a-SL that is immunoreactive towards all PTPRR proteins.

Figure 3: Immunolocalization of PTPRR protein in Mouse brain. Brain cryosections were stained using a mixture of three different monoclonal antibodies (1E3, 3E11 and 6A6) immunoreactive towards the common part in PTPRR isoforms and that cross-react with STEP. Positive staining is observed in the Purkinje cells of the cerebellum (A), both the neurones and neuropil of the striatum (B). The staining of the striatum reflects STEP immunoreactivity.
