    Product Information

    Product Description

    The PathScan® Phospho-SMAD2 (Ser465/467)/SMAD3 (Ser423/425) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that recognizes endogenous levels of phospho-SMAD2 (Ser465/467) and SMAD3 (Ser423/425) proteins. A SMAD2/3 Mouse Antibody has been coated on the microwells. After incubation with cell lysates, SMAD2/3 proteins (phospho and nonphospho) are captured by the coated antibody. Following extensive washing, a Phospho-SMAD2 (Ser465/467)/SMAD3 (Ser423/425) Detection Antibody is added to detect captured phospho-SMAD2 (Ser465/467) and phospho-SMAD3 (Ser423/425) proteins. Anti-rabbit IgG, HRP-linked Antibody is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of the absorbance for this developed color is proportional to the quantity of phospho-SMAD2 (Ser465/467) and phospho-SMAD3 (Ser423/425) proteins.

    *Antibodies in this kit are custom formulations specific to kit.

    Protocol

    Specificity / Sensitivity

    PathScan® Phospho-SMAD2 (Ser465/467)/SMAD3 (Ser423/425) Sandwich ELISA Kit recognizes endogenous levels of phospho-SMAD2 (Ser465/467) and SMAD3 (Ser423/425) proteins in human cells, as shown in Figure 1. The kit sensitivity is shown in Figure 2. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

    Human, Mouse, Mink

    Background

    Members of the SMAD family of signal transduction molecules are components of a critical intracellular pathway that transmit TGF-β signals from the cell surface into the nucleus. Three distinct classes of SMADs have been defined: the receptor-regulated SMADs (R-SMADs), which include SMAD1, 2, 3, 5, and 9; the common-mediator SMAD (co-SMAD), SMAD4; and the antagonistic or inhibitory SMADs (I-SMADs), SMAD6 and 7 (1-5). Activated type I receptors associate with specific R-SMADs and phosphorylate them on a conserved carboxy-terminal SSXS motif. The phosphorylated R-SMADs dissociate from the receptor and form a heteromeric complex with SMAD4, initiating translocation of the heteromeric SMAD complex to the nucleus. Once in the nucleus, SMADs recruit a variety of DNA binding proteins that function to regulate transcriptional activity (6-8).
