Acetylates histones, giving a specific tag for transcriptional activation. Also acetylates non-histone proteins, like NCOA3 coactivator. Binds specifically to phosphorylated CREB and enhances its transcriptional activity toward cAMP-responsive genes. Acts as a coactivator of ALX1 in the presence of EP300.
CREBBP Antibody (Ab097687) - Western Blot All lanes: CREBBP Antibody (Ab097687) at 1/1000 dilution Samples: Lysates at 20 µg per lane Secondary: Goat Anti-Rabbit IgG H&L (HRP) (Ab170144) at 1/10000 dilution Predicted band size: 265 kDa Observed band size: 100, 150, 270 kDa Exposure time: 223.0 s
CREBBP Antibody (Ab097687) - IHC Immunohistochemical analysis of CBP staining in human tonsil formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0). The section was then incubated with CREBBP Antibody (Ab097687) 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.
CREBBP Antibody (Ab097687) - IF/ICC Immunofluorescent analysis of CBP staining in A431 cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with CREBBP Antibody (Ab097687) in 3% BSA-PBS and incubated overnight at 4 °C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight 594-conjugated secondary antibody (red) in PBS at room temperature in the dark.
