    Immunohistochemical analysis of 4% PFA fixed 0.2% Triton X-100 permeabilized frozen Rat E14.5 cerebrum tissue labeling EOMES with ab216870 at 1/100 (5.75 µg/ml) dilution followed by ab150077 AlexaFluor®488 Goat anti-Rabbit secondary at 1/1000 (2 µg/ml) dilution. The nuclear counterstain was DAPI (Blue). Heat mediated antigen retrieval using sodium citrate buffer (10mM citrate pH 6.0 + 0.05% Tween-20). Positive staining in rat embryonic cerebrum (PMID: 24223221) is observed.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody was ab150077 AlexaFluor®488 Goat anti-Rabbit secondary at 1/1000 (2 µg/ml) dilution.

    Immunohistochemical analysis of paraffin-embedded E14.5 rat cerebral cortex tissue labeling EOMES with ab216870 at 1/1000 dilution followed by a ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101). Nuclear staining on E14.5 rat cerebral cortex (PMID: 18725516) is observed.  The section was incubated with ab216870 for 30 mins at RT. The immunostaining staining was performed on a Leica Biosystems BOND® RX instrument. Counterstained with Hematoxylin.

    Secondary antibody only control: Secondary antibody is a ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101).

    Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution 2) for 20 mins.

    Immunofluorescent analysis of 4% Paraformaldehyde-fixed, 0.1% TritonX-100 permeabilized NK-92 (human malignant non-Hodgkin's lymphoma natural killer cell) cells labelling EOMES with ab216870 at 1/100 dilution, followed by ab150077 AlexaFluor®488 Goat anti-Rabbit secondary antibody at 1/1000 dilution (Green). Confocal image showing nuclear staining in NK-92 cell line is observed. Ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) was used to counterstain tubulin at 1/200 dilution (Red). The Nuclear counterstain was DAPI (Blue).

    Secondary antibody only control: Secondary antibody is ab150077 AlexaFluor®488 Goat anti-Rabbit secondary at 1/1000 dilution.

  • Immunoprecipitation - Anti-TBR2 / Eomes antibody [EPR21950-241] (ab216870)
    Immunoprecipitation - Anti-TBR2 / Eomes antibody [EPR21950-241] (ab216870)

    TBR2 / Eomes was immunoprecipitated from 0.35 mg NK-92 (Human malignant non-Hodgkin's lymphoma natural killer cell) whole cell lysate 10μg with ab216870 at 1/30 dilution (2μg in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab216870 1/500 dilution (1.2 μg/ml). VeriBlot for IP Detection Reagent (HRP) (ab131366) was used as the secondary antibody at 1/1000 dilution.

    Lane 1: NK-92 (Human malignant non-Hodgkin's lymphoma natural killer cell) whole cell lysate 10μg

    Lane 2: ab216870 IP in NK-92 whole cell lysate

    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab216870 in NK-92 whole cell lysate.

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.

    Exposure time: 3 min

    Lysates were made fresh and used in IP test immediately to minimize protein degradation. Incubation time was 2h.

    Under these experimental conditions ab216870 enriches for the 75kDa Eomes protein in IP.

    This band size (75kDa) is consistent with what has been described in the literature (PMID: 26749212).
