Human Mothers Against Decapentaplegic Homolog 7 (Smad7) ELISA Kit
Principle of the Assay
The microtiter plate provided in this kit has been pre-coated with an antibody specific to Smad7. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to Smad7. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After the TMB substrate solution is added, only those wells that contain Smad7, biotin-conjugated antibody, and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution, and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Smad7 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
For Use with serum, plasma, and cell culture supernatants. For Research Use Only. Not for use in diagnostic procedures.
Target Information
Antagonist of signaling by TGF-beta (transforming growth factor) type 1 receptor superfamily members; has been shown to inhibit TGF-beta (Transforming growth factor) and activin signaling by associating with their receptors thus preventing SMAD2 access. Functions as an adapter to recruit SMURF2 to the TGF-beta receptor complex. Also acts by recruiting the PPP1R15A-PP1 complex to TGFBR1, which promotes its dephosphorylation. Positively regulates PDPK1 kinase activity by stimulating its dissociation from the 14-3-3 protein YWHAQ which acts as a negative regulator.

Performance Characteristics
REPEATABILITY |
Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level Smad7 were tested 20 times on one plate, respectively. |
SENSITIVITY | The minimum detectable dose was 0.056ng/mL. |
ASSAY RANGE | 0.156-10ng/mL |
SPECIFICITY | This assay has high sensitivity and excellent specificity for the detection of Smad7. No significant cross-reactivity or interference between Smad7 and analogs was observed. Note: Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between Smad7 and all analogs, therefore, cross reactivity may still exist. |
