    Product Information

    Storage

    Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

    Specificity / Sensitivity

    Phospho-(Ser/Thr) Akt Substrate Antibody can be used in high throughput kinase assays and drug discovery applications. This antibody preferentially recognizes peptides and proteins containing phospho-Ser/Thr preceded by Lys/Arg at positions -5 and -3, in a manner largely independent of other surrounding amino acids. Some cross-reactivity is observed for peptides that contain phospho-Ser/Thr preceded by Arg/Lys at positions -3 and -2. No cross-reactivity is observed with the corresponding nonphosphorylated sequences or with other phospho-Ser/Thr-containing motifs. By ELISA, this antibody recognizes a wide range of phosphorylated Akt substrate peptides.

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with synthetic phospho-Akt substrate peptides. Antibodies are sequentially purified by protein A and peptide affinity chromatography.

    Background

    An important class of kinases, referred to as Arg-directed kinases or AGC-family kinases, includes cAMP-dependent protein kinase (PKA), cGMP-dependent protein kinase (PKG), protein kinase C, Akt, and RSK. These kinases share a substrate specificity characterized by Arg at position -3 relative to the phosphorylated Ser or Thr (1,2). Akt plays a central role in mediating critical cellular responses including cell growth and survival, angiogenesis, and transcriptional regulation (3-5). While a number of Akt substrates are known (such as GSK-3, Bad, and caspase-9) many important substrates await discovery. Akt phosphorylates substrates only at Ser/Thr in a conserved motif characterized by Arg at positions -5 and -3 (6). Phospho-Akt substrate-specific antibodies from Cell Signaling Technology are powerful tools for investigating the regulation of phosphorylation by Akt and other Arg-directed kinases, as well as for high throughput kinase drug discovery.
    Description: This antibody is formulated in PBS (no BSA/no glycerol) and quality controlled for ELISA and other drug discovery applications. This is a sample antibody and intended for use by drug discovery scientists.
