SOST Protein, Rat (Myc, His)

SOST protein inhibits bone growth by suppressing Wnt signaling and interacting with LRP4 and LRP5. Its interactions with LRP4 and LRP5 play crucial roles in suppressing Wnt signaling. The involvement of SOST in interactions with LRP6 highlights its regulatory role in bone growth. SOST Protein, Rat (Myc, His) is the recombinant rat-derived SOST protein, expressed by E. coli , with N-His, C-Myc labeled tag.

SOST protein serves as a negative regulator of bone growth by actively inhibiting Wnt signaling and bone formation. Its interaction with LRP4, facilitated through the extracellular domain, plays a crucial role in suppressing Wnt signaling. Additionally, SOST interacts with LRP5, specifically through the first two YWTD-EGF repeat domains, resulting in the inhibition of Wnt-mediated signaling. The involvement of SOST in interactions with LRP6 further underscores its regulatory role in the intricate network of molecular events that govern bone growth and development.

Approximately 34 kDa, based on SDS-PAGE under reducing conditions.

≥ 90%, as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of 10 mM Tris-HCl, 1 mM EDTA, 6% trehalose, pH 8.0.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
