Product Overview
Clone DCO-3 is a rabbit monoclonal antibody that recognizes cyclic AMP-responsive element-binding protein 1 (gene CREB1) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, immunoprecipitation and flow cytometry. The predicted molecular weight is 36.7 kDa, and the supplier reports an observed band at about 45 kDa.
CREB (CREB1) is a transcription factor that binds cAMP response elements (CRE) in gene promoters. Phosphorylation at Ser133 by PKA and other kinases recruits the coactivators CBP and p300 to switch on target genes, and CREB is widely studied in neuronal plasticity, memory, metabolism and cell survival.

Samples with a confirmed band (WB): NIH/3T3 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Samples with confirmed staining (IHC): mouse brain tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Samples with confirmed staining (ICC/IF): HeLa cells.
Immunogen
Synthetic peptide based on the sequence of human CREB.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places cyclic AMP-responsive element-binding protein 1 in the nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
