Our Abpromise guarantee covers the use of ab32503 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IHC-P||1/250. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.|
|WB||1/1000 - 1/10000. Detects a band of approximately 21 kDa (predicted molecular weight: 21 kDa).|
|Sandwich ELISA||Use at an assay dependent concentration. Can be paired for Sandwich ELISA with Mouse monoclonal [2D2] to Bax (ab77566).|
Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: Bax knockout HAP1 cell lysate (20 µg)
Lanes 1 - 2: Merged signal (red and green). Green - ab32503 observed at 20 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab32503 was shown to recognize Bax when Bax knockout samples were used, along with additional cross-reactive bands. Wild-type and Bax knockout samples were subjected to SDS-PAGE. ab32503 and ab8245 (loading control to GAPDH) were diluted at 1/1000 and 1/10 000 respectively and incubated overnight at 4°C. Blots were developed with goat anti-rabbit IgG (H + L) and goat anti-mouse IgG (H + L) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.
IHC image of ab32503 staining Bax in rat kidney 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 ab32503, 1:250 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. No primary antibody was used in the secondary only control (shown on the inset).
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.
