This data was developed using ab79698, the same antibody clone in a different buffer formulation.

This data was developed using ab79698, the same antibody clone in a different buffer formulation.Immunofluorescence staining of HeLa cells with purified ab79698 at a working dilution of 1/500, counter-stained with DAPI. The secondary antibody was an Alexa Fluor^® 488 conjugated goat anti-rabbit (ab150077), used at a dilution of 1/1000. The cells were fixed in 4% PFA and permeabilized using 0.1% Triton X 100. The negative control is shown in bottom right hand panel - for the negative control, PBS was used instead of the primary antibody.

This data was developed using ab79698, the same antibody clone in a different buffer formulation.Overlay histogram showing HeLa cells stained with ab79698 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab79698, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was DyLight^® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x10⁶ cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HeLa cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
