CREB (phospho-S133) antibody

Research Area

Stem Cell & Developmental Biology

Images & Validation

• Tested Applications: ELISA, IHC, WB
• Dilution Range: ELISA: 1:1,000 - 1:6,000, IHC: 20 µg/ml, WB: 1:500 - 1:2,000
• Reactivity: Human, Mouse, Rat
• Application Notes:
  Anti-CREB pS133 antibody reacts with phosphorylated human CREB at pS133 and shows minimal reactivity by western blot with non-phosphorylated CREB and minimal reactivity (1%) by ELISA against the non-phosphorylated form of the immunizing peptide. This antibody was assayed against a variety of tissues including fibroblasts and B-cell lysates. Bands of 46 and 43 kDa corresponding to phosphorylated CREB are observed in western blots. Anti-CREB pS133 is suitable for the detection by immunoblot of phosphorylated human, mouse and rat CREB. No cross-reactivity occurs with non-phosphorylated CREB. For immunohistochemistry, formalin fixed, paraffin embedded human tissue shows moderate to strong nuclear staining in a variety of cells with minimal background staining. Although not tested this antibody is likely functional by FACS and immunoprecipitation.

Key Properties

• Antibody Type: Primary Antibody
• Host: Rabbit
• Clonality: Polyclonal
• Isotype: IgG
• Immunogen: CREB phospho peptide corresponding to amino acid residues 122-147 of the human protein conjugated to Keyhole Limpet Hemocyanin (KLH).
• Target: CREB1
• Purity: Anti-CREB pS133 was affinity purified from monospecific antiserum by immunoaffinity purification. Antiserum was first sequentially pre-adsorbed against a control E.coli lysate, nickel-purified recombinant CREB and the non-phosphorylated form of the immunizing peptide. The resultant depleted antiserum was then purified against the phosphorylated form of the immunizing peptide. This phospho specific polyclonal antibody is specific for phosphorylated pS133 of human CREB. Reactivity with non-phosphorylated CREB is minimal. This antibody does show cross reactivity with pS133 phosphorylated CREB from mouse and rat.
• Conjugation: Unconjugated
