Mini Sample Mouse SOST ( Sclerostin ) ELISA Kit (E-MSEL-M0099)

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to SOST . Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for SOST and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain SOST , biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of SOST . You can calculate the concentration of SOST in the samples by comparing the OD of the samples to the standard curve.

Sclerostin is a secreted glycoprotein with a C-terminal cysteine knot-like ( CTCK ) domain and sequence similarity to the DAN ( differential screening-selected gene aberrative in neuroblastoma ) family of bone morphogenetic protein ( BMP ) antagonists. Loss-of-function mutations in this gene are associated with an autosomal-recessive disorder , sclerosteosis , which causes progressive bone overgrowth. A deletion downstream of this gene , which causes reduced sclerostin expression , is associated with a milder form of the disorder called van Buchem disease.
