Product Details

Molecular Aliases
sclerostin; SOST; VBCHsclerosteosis; CDD; DAND6; SOST1; VBCH
Protein Length
Gln24-Tyr213
Expression System
HEK293
Theoretical Molecular Weight
The protein has a predicted MW of 24.2 kDa. Due to glycosylation,the protein migrates to 28-40 kDa based on Bis-Tris PAGE result.
Purity
> 95% as determined by Bis-Tris PAGE
Endotoxin
Less than 1 EU per μg by the LAL method.
Buffer / Formulation
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
State
Lyophilized
Storage Conditions
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Reconstitution Advice
Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

Background

SOST, also known as sclerostin, is a member of the cerberus/DAN family, a group of secreted glycoproteins characterized by a cysteine-knot motif. SOST is negative regulator of bone growth that acts through inhibition of Wnt signaling and bone formation.
