This monoclonal antibody to p53 has been knockout validated in Western blot and ICC/IF. The expected signal for p53 was observed in wild type cells and the signal was not seen in knockout cells.
Product was previously marketed under the MitoSciences sub-brand.
This antibody clone is manufactured by Abcam.
Our Abpromise guarantee covers the use of ab154036 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 2 µg/ml. Detects a band of approximately 53 kDa.|
|IP||Use at an assay dependent concentration.|
|Flow Cyt||Use at an assay dependent concentration.
ab170191 - Mouse monoclonal IgG2a, is suitable for use as an isotype control with this antibody.
|In-Cell ELISA||Use at an assay dependent concentration.|
|ICC/IF||Use a concentration of 1 µg/ml.|
|IHC-P||Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.|
Lanes 1, 5 and 9: Wild-type HAP1 cell lysate (20 µg)
Lanes 2, 6 and 10: p53 knockout HAP1 cell lysate (20 µg)
Lanes 3, 7 and 11: A431 cell lysate (20 µg)
Lanes 4, 8 and 12: Saos-2 cell lysate (20 µg)
Lanes 1, 2, 3 and 4: Green signal from target – ab154036 observed at 53 kDa
Lanes 5, 6, 7 and 8: Red signal from loading control – ab181602 observed at 37 kDa
Lanes 9, 10, 11 and 12: Merged (red and green) signal
ab154036 was shown to specifically react with p53 in wild type HAP1 cells. No band was observed when p53 knockout samples were used. Wild-type and p53 knockout samples were subjected to SDS-PAGE. ab154036 and ab181602 (loading control to GAPDH) were diluted 2 µg/mL and 1/10000 respectively and incubated overnight at 4ºC. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preadsorbed ab216772 and Goat Anti-Rabbit IgG H&L (IRDye® 680RD) preadsorbed ab216777 secondary antibodies at 1/10000 dilution for 1 h at room temperature before imaging.
ab154036 staining p53 in wild-type HAP1 cells (top panel) and p53 knockout HAP1 cells (bottom panel). The cells were fixed with 4% formaldehyde (10min), 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 ab154036 at 1μg/ml concentration and ab202272 at 1/250 dilution (shown in pseudo colour red) overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to Mouse IgG (Alexa Fluor® 488) (ab150117) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.
IHC image of ab154036 staining beta Catenin in human colon adenocarcinoma formalin-fixed paraffin-embedded tissue sections*, performed on a Leica Bond. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab154036, 1/500 dilution, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. High magnification of the tumor region - T (lower right panel) and adjacent normal crypts - N (lower left panel) are shown.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
