issue: Sf-1:Cre mice crossed to the Z/EG reporter line. Mouse brain (coronal view, 20X magnification). Fixation: 4%PFA/PBS with o/n fixation, and subsequently transferred to a 30% sucrose solution. Antigen retrieval: frozen in OCT freezing medium (Sakura) and cryostat sectioned at 40 microns. Goat anti-GFP was used at 1:500 dilution in free floating imunnohistochemistry to detect GFP. Fluorchrome conjugated Anti-goat IgG secondary antibody was used for detection at 1:500 at 1:10,000 for 45 min at RT. Localization: Sf-1+ neurons and their processes of the ventromedial nucleus of the hypothalamus. Staining: eGFP as green fluorescent signal and sections were counterstained with DAPI.
Tissue: Drosophila melanogaster late stage embryonic central nervous system. Fixation: 0.5% PFA. Antigen retrieval: not required. Anti-GFP antibody at a 1:1,000 for 1 h at RT. AlexaFluor 488 conjugated anti-Goat antibody at 1:300 for 45 min at RT. Panel A: shows a lateral view (ventral left). Panels B and C: shows ventral views of whole mount embryos at 63x magnification (plus 2x digital zoom). In all panels, anterior is up. Staining: tau-GFP cell bodies (large arrowhead) and axons of motorneurons (arrow) and interneurons (small arrowhead) as green fluorescent signal.

Western Blot of GFP antibody. Lane 1: HeLa cells. Lane 2: mock transfected HeLa cell lysate. Load: 35 ug per lane. GFP antibody at 1 ug/ml for 1 h at room temperature. IRDye 800 conjugated Donkey-a-Goat IgG [H&L] MX7 (605-732-125) secondary antibody at 1:2,500 for 45 min at RT. Block: 5% Blocking buffer overnight at 4 deg C. Size: 27 kDa, 33 kDa for GFP..
