Localization of BAI1, Noggin, Iba1, NeuN and GFAP in the mouse brain.
Tissue sections from the day-10 mouse brain were stained with hematoxylin and eosin (sagittal sections A and D; coronal sections B and C) or double labeled with the G8 and the R&D BAI1 mAbs, or G8 and antibodies to Iba1, NeuN or GFAP. The areas within the boxes of the H&E stained sections are shown at high magnification in the fluorescence photomicrographs. The colors of the fluorescent secondary antibodies are indicated in the unmerged photographs (E, F, H and I). Nuclei were stained with Hoechst dye. Overlap of red and green, when present, appears yellow in merged images (G, J, K, L and M). The G8 and BAI1 mAbs labeled the same subpopulation of cells in the hippocampal formation (box in A; E-G). The Noggin and BAI1 antibodies also bound to the same cells in the glomerular layer of the olfactory bulb (box in B; H-J). G8 did not co-localize with Iba1 (K, from box in A), NeuN (L from lower box in C) or GFAP (M from box in D). Minimal fluorescence was observed with the anti-IgM and anti-IgG (inset in G) or the anti-goat and anti-IgG (inset in J) secondary antibodies. Bar = 270 μM in A-D and 9 μM in E-M.
