Clone EPR16667 (ab215263) has been successfully conjugated by Abcam. This image was generated using Anti-MEK1 + MEK2 antibody [EPR16667] (PE). Please refer to ab225265 for protocol details.

Overlay histogram showing A431 cells stained with ab225265 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab225265, 1/1000 dilution) for 30 min at 22°C.

Isotype control antibody (black line) was Rabbit IgG (monoclonal) Phycoerythrin (ab209478) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

Acquisition of >5,000 events were collected using a 50 mW Yellow/Green laser (561nm) and 586/15 bandpass filter.

This antibody gave a positive signal in A431 cells fixed with 4% formaldehyde (10 min)/permeabilized with 0.1% PBS-Triton X-100 for 15 min used under the same conditions.

Clone EPR16667 (ab215263) has been successfully conjugated by Abcam. This image was generated using Anti-MEK1 + MEK2 antibody [EPR16667] (Alexa Fluor® 488). Please refer to ab200177 for protocol details.

ab200177 staining MEK1 + MEK2 in A431 cells. The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab200177 at a 1/100 dilution (shown in green) and ab195889, Mouse monoclonal to alpha Tubulin (Alexa Fluor^® 594), at a 1/250 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).

Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

Immunohistochemical analysis of paraffin-embedded Human renal medulla tissue labeling MEK1 + MEK2 with ab178876 at 1/500 dilution, followed by prediluted HRP Polymer for Rabbit/Mouse IgG. Renal tubule epithelial cells show strong cytoplasmic staining with some additional nuclear staining. Counter stained with Hematoxylin.

Negative control : Using PBS instead of primary ab, secondary ab is prediluted HRP Polymer for Rabbit/Mouse IgG.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab178876).
