SOST Protein, Human, Recombinant (His & Avi), Biotinylated

Catalog No. TMPK-00103

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. SOST Protein, Human, Recombinant (His & Avi), Biotinylated is expressed in HEK293 mammalian cells with N-His-Avi tag. The predicted molecular weight is 24.2 kDa and the accession number is Q9BQB4-1.

Description	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. SOST Protein, Human, Recombinant (His & Avi), Biotinylated is expressed in HEK293 mammalian cells with N-His-Avi tag. The predicted molecular weight is 24.2 kDa and the accession number is Q9BQB4-1.
Species	Human
Expression System	HEK293 Cells
Tag	N-His-Avi
Accession Number	Q9BQB4-1
Synonyms	VBCHsclerosteosis,VBCH,SOST1,SOST,sclerostin,DAND6,CDD
Construction	Gln24-Tyr213
Protein Purity	> 95% as determined by Tris-Bis PAGE
Molecular Weight	24.2 kDa (predicted). Due to glycosylation,the protein migrates to 28-40 kDa based on Tris-Bis PAGE result.
Endotoxin	< 1 EU/μg by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
Research 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.
