Image mosaic of a section through striatum showing localization of alpha synuclein in a wild type mouse. Dark area in upper right (cortex) results from unevenness in section flatness rather than lack of staining in this area. This mosaic image has been downsampled from the raw data image, which can be accessed using the link provided to the Cell Centered Database.

Wild type adult female mouse was anesthetized with nembutal, and perfused with 4% paraformaldehyde + 0.1% glutaraldehyde, followed by 1 hr. postfixation in 4% paraformaldehyde. Tissue was sectioned on a vibratome at a thickness of 80µm. Following rinses in phosphate buffer (PBS), sections were blocked (PBS with 3% NGS;1% fish gel, 0.1% Triton X-1000; 1% BSA) for 1 hour, followed by rinses in working buffer (1:10 blocking buffer: PBS). Primary antibody was diluted in working buffer (anti-alpha-SYN; Host = Rabbit used at 1:500), and tissue was covered with aluminum foil and incubated on a shaker in cold room overnight. Tissue was washed with working buffer and incubated in secondary antibody (goat anti-rabbit AlexaFluor 568, 1:50) covered with foil, on cold room shaker, 48 hrs. After rinses, 1:100 Hoescht 33342 was used to stain nuclei (30 min). After rinsing in PBS, sections were mounted on slides and coverslipped using Gelvatol. Sections were imaged using a BioRad RTS 2000MP Multiphoton, with a Nikon Plan Fluor 40X, NA 1.3 objective.
