Article Snippet: The following primary antibodies were used: rabbit anti-cFos (1:1000, #2250, Cell Signaling Technology), rabbit anti-BDNF(1:200, ANT-010, Alomone Labs), goat anti-GFP (1:1000, 51370, ROCKLAND), rabbit anti-ER alpha (1:500, NBP1-84827), chicken anti-mCherry (1:500, MCHERRY-0020, aves labs).The next day, sections were rinsed three times in PBS with 0.1% Triton X-100 and incubated with secondary antibodies prepared in the same diluent (secondary antibody, 5% normal donkey serum, 0.1% Triton X-100 in PBS).
