CREB1 (cyclic AMP-responsive element-binding protein 1) serves as a pivotal transcription factor that translates extracellular signals into changes in gene expression. By binding to cAMP response elements in target gene promoters, CREB1 regulates diverse cellular processes including neuronal plasticity, memory formation, and immune cell function. Its central role in signal transduction pathways makes it an essential target for researchers investigating epigenetics, nuclear signaling, and immunological responses.
This recombinant monoclonal antibody, generated from clone 21E3, offers the reproducibility and consistency that demanding experimental workflows require. Because recombinant antibodies are produced from defined genetic sequences rather than traditional hybridoma methods, you can expect uniform performance across different lots, eliminating the variability that can compromise longitudinal studies or multi-site collaborations. The rabbit IgG format and affinity-chromatography purification ensure high specificity for your target.
Validation studies demonstrate reliable performance across multiple experimental platforms. In western blot applications, this antibody detects CREB1 at the expected 36 kDa molecular weight in human cell lines including K562 and THP-1, as well as in mouse and rat brain tissue lysates, confirming robust cross-species reactivity for comparative studies. Flow cytometry validation in Jurkat cells shows clear separation between specific staining and isotype control, supporting intracellular detection workflows for analyzing CREB1 expression at the single-cell level.
Whether you are examining CREB1 activation in neurological disease models, characterizing its role in immune cell differentiation, or investigating epigenetic regulation, this antibody provides the flexibility to move between protein quantification by western blot and population-level analysis by flow cytometry within a single research program.
