Immunohistochemical localization of cyclic GMP in rat cerebellum.
The technique of cyclic nucleotide fluorescence immunohistochemistry has been applied for the specific localization of cyclic GMP in rat cerebellum. We report immunofluorescence associated with fibres and membranes, contrasting with previously reported cytoplasmic localization of cyclic AMP in different cell populations, using a similar technique. We have been unable to detect changes in cyclic GMP staining in response to post-mortem changes, harmaline and pentobarbitone administration. A role of cyclic GMP is suggested in membrane ion transport.
