Active Recombinant Human RSPO1

• Cat.No.: RSPO1-351H
• Product Overview: Recombinant Human RSPO1 (NP_001033722.1) (Met 1-Ala 263) was produced in CHO Cells.

Specification

• Source: CHO
• Species: Human
• Tag: N/A
• Form: Lyophilized from sterile 50 mM Tris, pH 8.0.
  Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: Measured by its ability to induce activation of ßcatenin response in a Topflash Luciferase assay using HEK293T human embryonic kidney cells. The ED50 for this effect is typically 10-80 ng/mL in the presence of 5 ng/mL recombinant mouse Wnt3a.
• Molecular Mass: The recombinant human RSPO1 consists of 243 amino acids and has a predicted molecular mass of 26.8 kDa. As a result of glycosylation, the apparent molecular mass of it is approximately 40 and 31 kDa in SDS-PAGE under reducing conditions.
• Protein Length: Met1-Ala263
• Endotoxin: < 10 EU per mg protein.
• Purity: ≥ 95 % as determined by SDS-PAGE. ≥95% as determined by SEC-HPLC
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
