    Product Information

    Product Description

    This Cell Signaling Technology® antibody is the biotinylated version of the unconjugated Phospho-CREB (Ser133) (87G3) Rabbit Monoclonal Antibody #9198 and is expected to exhibit the same species cross-reactivity. The concentration of the biotinylated antibody is 500 ug/ml. Peptide ELISA data were generated using the biotinylated antibody. Western blot data were generated using the unconjugated antibody.
    MW (kDa) 43

    Product Usage Information

    Biotinylated antibodies are ideal for immunoassay technologies and high-throughput ELISA platforms that require antibody pairs where both antibodies are from the same host. Platforms utilizing biotinylated antibodies include, but are not limited to, MSD, xMAP, Quanterix Simoa, AlphaLISA, AlphaScreen, HTRF, LANCE, and TR-FRET.

    Optimal dilutions/working concentrations should be determined by the end user. Please contact us if you require the antibody clone biotinylated at a different concentration, a carrier-free formulation, or a more customized packaging solution.

    Storage

    Supplied in 140 mM NaCl, 3 mM KCl, 10 mM sodium phosphate (pH 7.4) dibasic, 2 mM potassium phosphate monobasic, 2 mg/mL BSA, and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

    Protocol

    Specificity / Sensitivity

    Phospho-CREB (Ser133) (87G3) Rabbit Monoclonal Antibody (Biotinylated) detects endogenous levels of CREB only when phosphorylated at Ser133. This antibody also detects the phosphorylated form of the CREB-related protein ATF-1.

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser133 of human CREB.

    Background

    CREB is a bZIP transcription factor that activates target genes through cAMP response elements. CREB is able to mediate signals from numerous physiological stimuli, resulting in regulation of a broad array of cellular responses. While CREB is expressed in numerous tissues, it plays a large regulatory role in the nervous system. CREB is believed to play a key role in promoting neuronal survival, precursor proliferation, neurite outgrowth, and neuronal differentiation in certain neuronal populations (1-3). Additionally, CREB signaling is involved in learning and memory in several organisms (4-6). CREB is able to selectively activate numerous downstream genes through interactions with different dimerization partners. CREB is activated by phosphorylation at Ser133 by various signaling pathways, including Erk, Ca2+, and stress signaling. Some of the kinases involved in phosphorylating CREB at Ser133 are p90RSK, MSK, CaMKIV, and MAPKAPK-2 (7-9).
