DKK3 ELISA Kit (Mouse)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Dickkopf Related Protein 3 (DKK3) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Dickkopf Related Protein 3 (DKK3) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Antagonizes canonical Wnt signaling by inhibiting LRP5/6 interaction with Wnt and by forming a ternary complex with the transmembrane protein KREMEN that promotes internalization of LRP5/6. DKKs play an important role in vertebrate development, where they locally inhibit Wnt regulated processes such as antero-posterior axial patterning, limb development, somitogenesis and eye formation. In the adult, Dkks are implicated in bone formation and bone disease, cancer and Alzheimer disease (By similarity) .

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Dickkopf Related Protein 3 (DKK3) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Dickkopf Related Protein 3 (DKK3) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Dickkopf Related Protein 3 (DKK3), 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 Dickkopf Related Protein 3 (DKK3) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
