They do not want to send me a free sample to Argentina and I have no references on whether it actually works on mouse brain tissue for immunofluorescence.
Besides the two publications listed at SCBT site (one of them shows immunohistochemical staining in spinal cord), a more recent article shows it is working in tumors. http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0166553 (figure 6a). This does not answer your question, and hopefully can add a bit to your consideration.
