Name :
Recombinant Human SOST/Sclerostin Protein (His Tag)
Biological Activity :
Background :
Sclerostin, the protein product of the SOST gene, is a potent inhibitor of bone formation. Sclerostin protein is widely expressed at low levels with highest levels in bone, cartilage, kidney, liver, bone marrow and primary osteeoblasts differentiated for 21 days, and was originally identified as an important regulator of bone remodeling, homeostasis, and links bone resorption and bone apposition. Recent studies have revealed that Sclerostin protein inhibits the bone growth probably by binding to the extracellular domain of the Wnt coreceptors LRP5 and LRP6 and disrupting Wnt-induced Frizzled-LRP complex formation.
Biological Activity :
1.Measured by its ability to inhibit Wnt3a induced alkaline phosphatase production by C3H10 T1/2 cells. The ED50 for this effect is typically 0.2-1μg/mL.2.Loaded Recombinant Human LRP-6 Protein, His & AVI Tag, Avi-tag Biotinylated (Cat. No. 11968-H49H-B) on SA Biosensor, can bind Recombinant Human SOST/Sclerostin Protein, His Tag (Cat. No. 10593-H07H) with an affinity constant of 39.5 nM as determined in BLI assay (Sartorius Octet RED384) (Routinely tested).
