Validation Data Gallery

• 

  WB analysis using 28792-1-AP

  Non-treated and Forskolin treated HSC-T6 cells were subjected to SDS PAGE followed by western blot with 28792-1-AP (Phospho-CREB1 (Ser133) antibody) at dilution of 1:4000 incubated at room temperature for 1 hours. The membrane was stripped and re-blotted with GAPDH antibody as loading control.

• 

  IHC staining of human liver using 28792-1-AP

  Immunohistochemical analysis of paraffin-embedded human liver tissue slide using 28792-1-AP (Phospho-CREB1 (Ser133) antibody) at dilution of 1:200 (under 40x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0).

Tested Applications

• Positive WB detected in: Forskolin treated HSC-T6 cells
• Positive IHC detected in: human liver tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0

Recommended dilution

• Western Blot (WB): WB : 1:1000-1:8000
• Immunohistochemistry (IHC): IHC : 1:50-1:500

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

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.
