Immunohistochemistry (Frozen sections) - Anti-TBR2 / Eomes antibody (AB23345)
Dlx2 and Tbr2 identify non overlapping progenitor lineages in the adult mouse SVZ (subventricular zone).
(A–B) Adult C57/BL6 mouse forebrain coronal sections at rostro-caudal point 1.2 relative to the bregma were immunostained for Dcx (red), Dlx2 or Tbr2 (green) and Ki67 (blue). Both progenitor populations show characteristics of migrating neuroblasts, as indicated by their Dcx expression (C–D). Adult Mash1 mouse forebrain coronal sections at rostro-caudal point 1.2 relative to the bregma were immunostained for Tbr2 (red) and Dlx2 (blue). Both Tbr2 and Dlx2 exhibited EGFP expression, but showed no colocalisation. Right side captions show cropped individual channels and the merges. Full panel insets are zoomed and cropped DAB stained photomicrographs of rostral periventricular sections for Tbr2 in the dorsal SVZ (A), Dlx2 in the dorso-lateral SVZ (B) and Mash1 in the ventro-lateral SVZ (C). Yellow arrows and arrowheads show respectively positive stained cell and low level TF staining. Dotted lines mark approximate boundaries of ventricular space. Flattened confocal z-stacks are of 14–15 μm thickness, including captions. Scale bars : 15 μm in full panels, 20 μm in captions and 25 μm in insets.

Immunohistochemistry (Frozen sections) - Anti-TBR2 / Eomes antibody (AB23345)
Immunofluorescence staining of TRB2 staining in a mouse brain E14 frozen tissue section.
The section was fixed using 10% formaldehyde in 1X PBS for 10 minutes. No antigen retrieval step was performed prior to staining. Performed on a Leica BONDTM. The section was incubated at room temperature for 1 hour with ab23345 at 1/100 dilution. Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody was used to detect the primary antibody (shown in green). Nuclear DNA was labelled with DAPI (shown in blue). The section was then mounted using Dako Fluorescence Mounting Medium®.
Image was 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.

Immunohistochemistry (Frozen sections) - Anti-TBR2 / Eomes antibody (AB23345)
IHC image of TRB2 staining in a mouse brain E14 frozen tissue section. The section was pre-treated using pressure cooker heat mediated antigen retrieval with sodium citrate buffer (pH6). Non-specific protein-protein interactions were then blocked in TBS containing 0.2% (v/v) Triton X-100 for 1h at room temperature. The section was then incubated overnight at +4°C in TBS containing 0.05% (v/v) Triton X-100 and 1% (w/v) BSA with ab23345 at 1/100 dilution. Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody was used to detect the primary antibody. The section was 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.

Biological function summary
TBR2 is important in controlling the transition of neural progenitors during cortical development. It serves as an important marker for intermediate neuronal precursors highlighting its importance in the progression from radial glia to neurons. TBR2 does not function in a complex but works closely with the transcription factor Neurogenin 2 to control neuronal differentiation. Its activity determines the timing of neuronal differentiation making it indispensable for orderly cortical layer formation.
Pathways
TBR2 is involved in the Wnt signaling and Notch signaling pathways both key regulators of neurodevelopment. In the Wnt pathway TBR2 influences the balance between progenitor cell proliferation and differentiation by interacting with proteins such as Beta-catenin. In the Notch signaling pathway TBR2 modulates neural precursor cell fate decisions often in relation with proteins like DLL1. These pathways ensure proper brain structure and function by coordinating neural progenitor activity.
