Optimized DNA sequence  encoding  extracellular domain of Human Sclerostin (GLN24 - TYR213) including a N-terminal His tag was expressed in HEK293 cells. 

Molecular weight:

Recombinant SOST is a  protein consisting of 195 amino acid residue subunits,  due to glycosylation migrates as an approximately 35kDa protein on SDS-PAGE.

>95%, as determined by SDS-PAGE and HPLC
Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/¬Ķg(1EU/¬Ķg).

Recombinant Human Sclerostin is lyophilized ¬†from 0.2 őľm filtered PBS solution, ¬†pH7.2 , ¬†5% Trehalose.

Recombinant¬†Sclerostin¬†can be stored in working aliquots at 2¬į - 8¬į C for one month, or at -20¬įC to¬†-70¬įC¬†for twelve months.

Avoid repeated freeze/thaw cycles.

Sclerostin is an endogenous antagonist secreted almost always exclusively by osteocytes, and it has been extensively studied as a major regulator of canonical Wnt pathway in bone metabolism . Sclerostin, an osteocyte- derived, secreted, cystine- knot protein inhibits bone formation by interacting with and altering the activity of bone morphogenetic proteins (BMPs), low-density lipoprotein-receptorĖrelated protein 5 (LRP 5/6), cysteine-rich protein 61, the receptor tyrosine kinase v-erb-b2 erythroblastic leukemia viral oncogene homolog 3 (erb B3), among other proteins.Inactivating mutations in the human sclerostin gene (SOST) are associated with sclerosteosis or van Buchem disease both of which are characterized by progressive overgrowth and sclerosis of the axial and appendicular skeleton and an increase in bone mineral density
