ICC/IF image of ab1647 stained human HeLa cells. The cells were PFA fixed (3.7% PFA, 10 min) and incubated with the antibody (ab1647, 5µg/ml) for 1h at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 WGA was used to label plasma membranes (red). The exact cellular location of p53 (phospho S315) is not currently well described so we cannot say for certain if the localisation of the primary in this analysis is correct. However, the control experiment using only the secondary antibody gave no signal in the Alexa Fluor® 488 channel so the signal seen in the image above is specific to ab1647.
