Validation Data Gallery

Filter:
  • Western Blot (WB) analysis of HEK-293 cells using Phospho-CREB1 (Ser133) Recombinant antibody (81871-1-RR)

    WB analysis of HEK-293 using 81871-1-RR (same clone as 81871-1-PBS)

    Non-treated and Calyculin A treated HEK-293 cells were subjected to SDS PAGE followed by western blot with 81871-1-RR (Phospho-CREB1 (Ser133) antibody) at dilution of 1:20000 incubated at room temperature for 1 hours. The membrane was stripped and re-blotted with Beta-tubulin antibody as loading control. This data was developed using the same antibody clone with 81871-1-PBS in a different storage buffer formulation.

  • Immunohistochemistry (IHC) staining of human prostate cancer tissue using Phospho-CREB1 (Ser133) Recombinant antibody (81871-1-RR)

    IHC staining of human prostate cancer using 81871-1-RR (same clone as 81871-1-PBS)

    Immunohistochemical analysis of paraffin-embedded human prostate cancer tissue slide using 81871-1-RR (Phospho-CREB1 (Ser133) antibody) at dilution of 1:2000 (under 40x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0). This data was developed using the same antibody clone with 81871-1-PBS in a different storage buffer formulation.

Background Information

The cAMP-response element binding protein (CREB) is localized in the nucleus and acts as a transcription factor, which binds to the cAMP response element (CRE) of the promoters of its target genes, upon phosphorylation at Ser133 by different receptor-activated protein kinases, such as protein kinase A (PKA), calmodulin-dependent protein kinase (CaMK), mitogen-activated protein kinases (MAPK), and other kinases. The activity of CREB1 in neurons has been correlated with various intracellular processes, including proliferation, differentiation, survival, long-term synaptic potentiation, neurogenesis, and neuronal plasticity. CREB1 belongs to the CREB/activating transcription factor (ATF) family of transcription factors. The antibody also detects the phosphorylated form of the CREB-related protein ATF1.
