Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CREBBP antibody [CBP5I001] (AB50702)

IHC image of CREBBP staining in human pancreas formalin fixed paraffin embedded tissue section, performed on a Leica Bond system using the standard protocol F. 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 ab50702, 10μg/ml, 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.

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.

Western blot - Anti-CREBBP antibody [CBP5I001] (AB50702)

Lane 1 : Wild-type HAP1 whole cell lysate (40 μg)
Lane 2 : CREBBP knockout HAP1 whole cell lysate (40 μg)
Lane 3 : HeLa whole cell lysate (40 μg)
Lane 4 : NIH3T3 whole cell lysate (40 μg)

Lanes 1 - 4 : Merged signal (red and green). Green - ab50702 observed at 265 kDa. Red - loading control, ab176560, observed at 50 kDa.

ab50702 was shown to specifically recognize CREBBP in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when CREBBP knockout samples were examined. Wild-type and CREBBP knockout samples were subjected to SDS-PAGE. ab50702 and ab176560 (Rabbit anti-alpha Tubulin loading control) were incubated overnight at 4°C at 1/100 dilution and 1/10,000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed ab216772 and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed ab216777 secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging.
