Spatial and temporal immunoreactivity in the rat brain using an affinity purified polyclonal antibody to DNSP-11.

ABSTRACT: DNSP-11 antibody signal was investigated in perfusion fixated Fischer 344 rat brains by immunohistochemistry with a custom, affinity purified polyclonal antibody. The DNSP-11-antibody signal was differentially localized from the mature GDNF protein both spatially and temporally. In the mesencephalon of post-natal day 10 animals, when GDNF is maximally expressed, DNSP-11 and GDNF antibody immunoreactivities co-localize extensively but not exclusively. In adult 3-month-old animals, GDNF expression is markedly reduced while the DNSP-11 signal remains intense. DNSP-11-antibody signal was present in the 3-month-old rat brain with signal in the substantia nigra, ventral tegmental area, dentate gyrus of the hippocampus, with the strongest signal observed in the locus ceruleus where GDNF is not ex
