    Product Information

    Product Usage Information

    Antibody pairs have been optimized using recommended buffers, reagents, plates and the included protocol. Solutions should be made fresh daily.

    Storage

    Capture and detection antibodies are stored at 4°C. HRP-linked secondary reagent is stored at -20°C.

    Protocol

    Product Description

    CST's PathScan® Phospho-p44/42 MAPK (Thr202/Tyr204) Sandwich ELISA Antibody Pair is offered as an economical alternative to our PathScan® Phospho-p44/42 MAPK (Thr202/Tyr204) Sandwich ELISA Kit #7177. Capture and detection antibodies (100X stocks) and an HRP-conjugated secondary antibody (1000X stock) are supplied. Sufficient reagents are supplied for 4 x 96 well ELISAs. The Phospho-p44/42 MAPK Rabbit Capture Antibody is coated in PBS overnight in a 96 well microplate. After blocking, cell lysate is added followed by a p44/42 MAPK Mouse Detection Antibody and an HRP-conjugated Anti-Mouse IgG Antibody. HRP substrate, TMB, is added for color development. The magnitude of the absorbance for this developed color is proportional to the quantity of p44/42 MAPK phosphorylated at Thr202/Tyr204.
    Antibodies in kit are custom formulations specific to kit.

    Specificity / Sensitivity

    For Antibody Pair specificity and sensitivity, please refer to the corresponding PathScan® Sandwich ELISA Kit. Note: This antibody pair detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

    Species Reactivity:

    Human, Mouse

    Background

    Mitogen-activated protein kinases (MAPKs) are a widely conserved family of serine/threonine protein kinases involved in many cellular programs, such as cell proliferation, differentiation, motility, and death. The p44/42 MAPK (Erk1/2) signaling pathway can be activated in response to a diverse range of extracellular stimuli, including mitogens, growth factors, and cytokines (1-3), and research investigators consider it an important target in the diagnosis and treatment of cancer (4). Upon stimulation, a sequential three-part protein kinase cascade is initiated, consisting of a MAP kinase kinase kinase (MAPKKK or MAP3K), a MAP kinase kinase (MAPKK or MAP2K), and a MAP kinase (MAPK). Multiple p44/42 MAP3Ks have been identified, including members of the Raf family, as well as Mos and Tpl2/COT. MEK1 and MEK2 are the primary MAPKKs in this pathway (5,6). MEK1 and MEK2 activate p44 and p42 through phosphorylation of activation loop residues Thr202/Tyr204 and Thr185/Tyr187, respectively. Several downstream targets of p44/42 have been identified, including p90RSK (7) and the transcription factor Elk-1 (8,9). p44/42 are negatively regulated by a family of dual-specificity (Thr/Tyr) MAPK phosphatases, known as DUSPs or MKPs (10), along with MEK inhibitors, such as U0126 and PD98059.
