  IHC image of TMEM119 staining in a section of Mouse cerebrum using ab209064 at 1:50 dilution.The section was fixed with 4% PFA then permeabilized with 0.2% Triton X-100. The secondary antibody was ab150081, Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed used at 1:1000 dilution. Nuclear DNA was labelled with DAPI (shown in blue). Heat mediated antigen retrieval using sodium citrate buffer (10mM citrate pH 6.0 + 0.05% Tween-20). Secondary antibody only control: PBS instead of the primary antibody.

• Immunohistochemistry (Frozen sections) - Anti-TMEM119 antibody [28-3] - Microglial marker (ab209064)

  IHC image of TMEM119 staining in a section of frozen normal mouse brain wild type (upper panel) and TMEM119 knockout (lower panel). No antigen retrieval step was performed prior to staining. Non-specific protein-protein interactions were then blocked in PBS containing 0.5% (v/v) Triton X-100, 0.3 M (w/v) glycine and 1% (w/v) BSA for 1 h at room temperature. The section was then incubated overnight at +4°C in PBS containing 0.5% (v/v) Triton X-100 and 1% (w/v) BSA with ab209064 at 0.5 µg/ml. The secondary antibody was ab150087 (shown in red) used at 2 µg/ml for1 hour at room temperature. Nuclear DNA was labelled with DAPI (shown in blue). The section was then mounted using Fluoromount®. Images were taken with a confocal microscope (Leica-Microsystems, TCS SP8).

  For other IHC staining systems (automated and non-automated), customers should optimize variable parameters such as antigen retrieval conditions, antibody concentrations and incubation times.

The section was then incubated overnight at +4°C in TBS containing 0.5% (v/v) Triton X-100 and 1% (w/v) BSA with ab209064 at 1 µg/ml and ab5076 at 5 µg/ml. The secondary antibodies were ab150087 (shown in red) and ab150133 (shown in green) used at 2 µg/ml for 1 hour at room temperature. Nuclear DNA was labelled with DAPI (shown in blue). The section was then mounted using Fluoromount®. Images were taken with a confocal microscope (Leica-Microsystems, TCS SP8).

• Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-TMEM119 antibody [28-3] - Microglial marker (ab209064)

  IHC image of TMEM119 staining in a section of formalin fixed, paraffin embedded normal mouse brain, performed on a Leica Bond™ system using the standard protocol B. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab209064, 0.5 µg/ml, for 15 mins at room temperature. A goat anti-Rabbit biotinylated secondary antibody was used to detect the primary, and visualized using an HRP conjugated ABC system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

  For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

  Representative FISH analysis of GAS5 (green) co‐stained with ab209064 (red) in spinal cord sections from EAE mice at 30dpi. Arrows indicate GAS5⁺TMEM119⁺cells. Scale bars=25μm.

  Female C57BL/6 mice (6–8 weeks) were deeply anesthetized with 3% chloral hydrate and a laminectomy was performed. After fixing the spine, 1μl of 1% lysolecithin in a 0.9% sodium chloride solution was injected into the dorsal funiculus at the level of the T11–T12 vertebrae. The day of lysolecithin injection was designated day 0 (0dpi).The spinal cord around the injection point was isolated and cut into serial cryosections.

  Tissue sections were fixed, permeabilized, and incubated with the primary antibody overnight at 4°C, followed by 2h of incubation with TRITC‐ or FITC‐conjugated secondary antibodies. Then, the samples were counterstained with Hoechst 33342.

  Representative images of sham (d–g) and hypoperfusion (h–k) at 12 weeks post-surgery are shown to illustrate Iba-1 immunostaining in sham (d) and hypoperfused (h); TMEM119 immunostaining in sham (e) and hypoperfused (i) and then Iba-1/TMEM119 co-localisation in sham (f,g) and hypoperfused (j,k) white matter. All Iba-1⁺cells in both sham and hypoperfused cohorts were also TMEM119⁺indicating that the cells in the corpus callosum were resident microglia. Scale bars; d-f and h-j are 50µm, g and k 10 µm. The number of microglial cells significantly correlated with nodal gap length.

  Free floating cryo-preserved sections cut at 30 μm thickness. Sections were incubated with the primary antibodies (anti-Iba-1 (1/100) and anti-TMEM119 (1/500, ab209064)) overnight at 4°C. Sections were stained at the outset with haematoxylin and eosin to determine the presence and absence of ischemic neuronal perikaryal damage as part of the inclusion/exclusion criteria.
