Our Abpromise guarantee covers the use of ab32515 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/500 - 1/1000. Detects a band of approximately 40 kDa (predicted molecular weight: 37 kDa).|
|ICC/IF||1/250 - 1/500.|
|IHC-P||Use at an assay dependent concentration.|
ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: CREB knockout HAP1 cell lysate (20 µg)
Lane 3: HeLa cell lysate (20 µg)
Lane 4: A431 cell lysate(20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab32515 observed at 44 kDa. Red - loading control, ab18058, observed at 214 kDa.
ab32515 was shown to recognize CREB in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when CREB knockout samples examined. Wild-type and knockout samples were subjected to SDS-PAGE. ab32515 and ab18058 (loading control to Vinculin) diluted to 1/500 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
ab32515 staining CREB in HeLa cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde and permeabilized with 0.5% Triton X-100 in PBS. Samples were incubated with primary antibody (1/500 in PBS) for 1 hour at 22°C. ab150081, an Alexa Fluor® 488-conjugated goat anti-rabbit IgG polyclonal (1/200) was used as the secondary antibody. Counterstained with DAPI.
