  Flow Cytometry - Anti-p53 antibody [E26] (ab32389)

  Flow cytometric analysis of 4% Paraformaldehyde fixed 90% Methanol permeabilized HEK-293 (Human embryonic kidney epithelial cell) cells labelling p53 with ab32389 at 1/500 dilution (1 μg/ml) compared with a Rabbit monoclonal IgG (Black) isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). A Goat anti rabbit IgG (Alexa Fluor® 488, Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) ab150077) at 1/2000 was used as the secondary antibody.

  Western blot - Anti-p53 antibody [E26] (ab32389)

  False colour image of Western blot: Anti-p53 antibody [E26] staining at 1/1000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab32389 was shown to bind specifically to p53. A band was observed at 49 kDa in wild-type A549 and Jurkat cell lysates with no signal observed at this size in tp53 knockout cell lines Human TP53 (p53) knockout A549 cell line ab276092, Human TP53 (p53) knockout Jurkat cell line ab276112 (knockout cell lysates ab282999, Human TP53 (p53) knockout Jurkat cell lysate ab283832). To generate this image, wild-type and tp53 knockout A549 and Jurkat cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3% milk in TBS-0.1 % Tween^® 20 (TBS-T) before incubation with primary antibodies overnight at 4°C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed (Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776) at 1/20000 dilution.

  Immunocytochemistry/ Immunofluorescence - Anti-p53 antibody [E26] (ab32389)

  ab32389 staining p53 in wild-type Hap1 cells (top panel) and p53 knockout Hap1 cells (bottom panel). The cells were fixed with 100% methanol (5 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 with ab32389 at 1μg/ml concentration and Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291 (Mouse monoclonal to alpha Tubulin) at 1/1000 dilution overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to rabbit IgG (Alexa Fluor® 488) (Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed ab150081) at 2 μg/ml (shown in green) and a goat secondary antibody to mouse IgG (Alexa Fluor® 594) (Goat Anti-Mouse IgG H&L (Alexa Fluor® 594) preadsorbed ab150120) at 2 μg/ml (shown in pseudo color red). Nuclear DNA was labelled in blue with DAPI.
  

  Image was taken with a high-content analysis system (Perkin Elmer, Operetta CLS™).

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human endometrium cancer tissue sections labelling p53 with purified ab32389 at 1/5000 dilution (0.09 μg/ml). Heat mediated antigen retrieval was performed using Heat mediated antigen retrieval using Bond™ Epitope Retrieval Solution 2 (pH 9.0) . Tissue was counterstained with Hematoxylin. Rabbit specific IHC polymer detection kit HRP/DAB (Rabbit specific IHC polymer detection kit HRP/DAB ab209101) secondary antibody was used at 1/0 dilution. PBS instead of the primary antibody was used as the negative control. The immunostaining was performed on a Leica Biosystems BOND® RX instrument.
