Immunohistochemical analysis of paraffin-embedded (A) 293T cells transfected with a human POLE (mutated P286R) expression vector containing a myc-His-tag®. (B) 293T cells transfected with a human wild-type POLE expression vector containing a myc-His-tag®. tissue labeling POLE (mutated P286R) with ab318136 at 1/2000 (0.268 ug/ml) dilution, followed by a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection).

Positive staining on (A) 293T cells transfected with a human POLE (mutated P286R) expression vector containing a myc-His-tag®, no staining on (B) 293T cells transfected with a human wild-type POLE expression vector containing a myc-His-tag®.
The section was incubated with ab318136 for 30 mins at room temperature.
The immunostaining was performed on a Leica Biosystems BOND® RX instrument.
Incubate slides with 3% Hydrogen Peroxide for 10 mins at room temperature after secondary antibody incubation to reduce the background

Counterstained with Hematoxylin.

Secondary antibody only control: Secondary antibody is a ready to use LeicaDS9800 (Bond™ Polymer Refine Detection).

Heat mediated antigen retrieval was performed with Tris-EDTA buffer (pH 9.0, Epitope Retrieval Solution2) for 20 mins.

Immunofluorescent analysis of 4% Paraformaldehyde-fixed, 0.1% TritonX-100 permeabilized 293T (human embryonic kidney epithelial cell) cells labelling POLE (mutated P286R) with ab318136 at 1/100 (5.36 ug/ml) dilution, followed by ab150081 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed antibody at 1/1000 2 ug/mL dilution (Green).

Confocal image showing nuclear staining in 293T cells (shown in green) transfected with a human POLE (mutated P286R) expression vector containing a Myc tag, and negative staining in 293T cells transfected with a wildtype POLE expression vector. The counterstain was observed in magenta. Nuclear DNA was labelled with DAPI (shown in blue). Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

ab223894 Anti-Myc tag mouse monoclonal antibody (Alexa Fluor® 594) was used to counterstain tubulin at 1/100 5ug/ml dilution (Magenta). The Nuclear counterstain was DAPI (Blue).

Secondary antibody only control: Secondary antibody is ab150081 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed at 1/1000 2 ug/mL dilution.

Flow cytometric analysis of 4% paraformaldehyde fixed 0.1% Tween-20 permeabilized 293T (human embryonic kidney epithelial cell) transfected with a human POLE (mutated P286R) containing a myc-His-tag® (upper right) / 293T transfected with a human wild-type POLE expression vector containing a myc-His-tag® (bottom left) / 293T transfected with an empty vector containing a myc-His-tag® (bottom right). cells labelling POLE (mutated P286R) with ab318136 at 1/500 dilution (0.1ug )/ Upper right, bottom left and bottom right (Red) compared with a Rabbit monoclonal IgG (ab172730) / Left isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue).

Goat Anti-Rabbit IgG (Alexa Fluor® 488, ab150081) at 1/5000 dilution was used as the secondary antibody.

POLE (mutated P286R) was immunoprecipitated from 0.35 mg 293T cells transfected with a human POLE (mutated P286R) expression vector containing a myc-His-tag®, whole cell lysate with ab318136 at 1/30 dilution (2ug in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab318136 at 1/1000 dilution. VeriBlot for IP secondary antibody(HRP)(ab131366) was used at 1/5000 dilution.
