    • WB: Human ES Cells treated with Retinoic Acid (24h) Whole Cell Lysate, Mouse Embryonic Brain (E14) Tissue Lysate. IHC-Fr: Mouse Embryonic Brain (E14.5).
  • 常规说明

    Tbr2 expression is observed in neuron progenitor compartments in development (the subventricular zone and ventricular zone) and expression rises and falls with cortical plate neurogenesis. Transition from radial glia to intermediate progenitor cell is associated with upregulation of Tbr2.

靶标

  • 功能
    Functions as a transcriptional activator playing a crucial role during development. Functions in trophoblast differentiation and later in gastrulation, regulating both mesoderm delamination and endoderm specification. Plays a role in brain development being required for the specification and the proliferation of the intermediate progenitor cells and their progeny in the cerebral cortex. Also involved in the differentiation of CD8+ T-cells during immune response regulating the expression of lytic effector genes.
  • 组织特异性
    Expressed in CD8+ T-cells.
  • 疾病相关
    Note=A translocation t(3;10)(p24;q23) located 215 kb 3' to the EOMES gene but leading to loss of its expression was identified in a large consanguineous family. Homozygous silencing produces microcephaly associated with corpus callosum agenesis, bilateral polymicrogyria, ventricular dilatation and a small cerebellum.
  • 序列相似性
    Contains 1 T-box DNA-binding domain.
  • 发展阶段
    Detected at 7 weeks of development in the forebrain floorplate of the CNS. Expressed within the mantle layer and migrating neuroblasts of the telencephalon at 12.5 weeks of development.

Anti-TBR2 / Eomes antibody - ChIP Grade 图像

  • Anti-TBR2 / Eomes antibody - ChIP Grade (ab23345) at 1 µg/ml + Human ES Cells treated with Retinoic Acid (24h) at 20 µg

    Secondary
    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed at 1/50000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 72 kDa
    Observed band size : 85 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 75 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 20 minutes

    This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% Milk before being incubated with ab23345 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406.

    Abcam recommends using milk as the blocking agent.

  • Antigen retrieval was carried out by microwaving sections in 0.01M sodium citrate (pH6.0) for 20 minutes. Sections were washed with PBS-0.01% Triton X-100 and then incubated for 30 minutes in blocking solution containing 20% goat or donkey serum, then incubated overnight at 4°C with ab23345 (1:100). Following incubation with ab23345, sections were washed in PBS-0.01% Triton X-100 and incubated with the secondary antibody donkey anti-rabbit Alexa Fluor 568 for 1 hour at room temperature. Nuclei were counterstained with TOPRO-3 (1:1000). Fluorescent images were captured using a Leica NTS confocal microscope.

  • ab23345 staining mouse developing cerebral cortex tissue sections by IHC-Fr.  Sections were PFA fixed and permeabilized in TX-100 prior to blocking with 2.5% serum for 1 hour at RT.  The primary antibody was diluted 1/500 and incubated with the sample for 18 hours.  A biotinylated pig anti-rabbit IgG antibody, diluted 1/500, was used as the secondary.

    ab23345 detects a clear band of ~ 72 kDa in lysates from EL4 cells expressing V5 tagged Eomesodermin (lane 2).  Lanes 1 and 3 contain lysates from EL4 cells expressing empty vector or V5 tag alone. Lanes 4-6 show the same lysates blotted with anti-V5 tag antibody. GAPDH was used as a loading control.
