Axonal tracks are negative eg:  Corpus callosum.

A very “nice ” positivity. Very similar to that in human and mouse testis, under identical conditions.

Is this specific?

Similar positivity seen as in human testis?

I am not familiar with c-fos expression patterns.

In this image there is a nuclear positivity mostly confined to the germinal layer of seminiferous tubules. Occasional Leydig cell nuclei are positive as is the cytoplasm of these cells.

Comments are welcome.

Fascin and DCX ( red).

SVZ  ( lateral ventricle).

Clear positivity in the lacteals’ endothelial cytoplasm

This antibody is not rat/mouse reactive in my laboratory, under identical conditions

Comments are welcome.

Non-reactive with mouse/rat, under same conditions.
