svz of Lateral ventricle, using VectorRed chorogen kit.

Note positive cells in the striatum: what are they?

The antibody is either of low sensitivity or the protein is very low copy-number because the positivity is moderate using a std stABCpx-DAB detection ( lower image). Using Nova red kit increased the signal significantly

Of course, one may use the higher sensitive DAB kits or, add  imidazole to your DAB solution.

Positivity in radial glia?

Developing Purkinje cells are positive, as well as what appear to be Granule cell fibres.

Stated as being human-reactive so my positivity may be non-specific.

However, there is a marked positivity within the progenitor OB interneurons. I am not sure if positivity is in these cells or, the associated astrocytes. The image shows that what appear to be core cells are negative ( cytoplasm of cells on both sides are positive).

svz region showing positive progenitor OB interneurons : upper positive cells are intensely +ve microglia. Second image shows this clearly

A remarkably different pattern of positivity v human testis.

Primary ab reagent should be diluted further to see if the moderate positivity is specific: if non-specific, the strong positivity of the basal spermatogonia should remain positive but the moderate positivity should be gone.

Microglia in wt rat brain: note the apparent intimate association with positive microglia and neurones.
