Active Recombinant Human DKK1 protein, His-tagged

• Cat.No.: DKK1-023H
• Product Overview: Recombinant Human DKK1 (NP_036374.1) (Met 2-His 266) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Source: HEK293
• Species: Human
• Tag: His
• 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 inhibit Wnt3a-induced alkaline phosphatase production by C3H10T1/2 cells. The ED50 for this effect is approximately 0.1-0.4 μg/ml in the presence of 10 ng/mL of mouse Wnt3a.
• Molecular Mass: The recombinant human DKK1 protein consists of 246 amino acids and has a calculated molecular mass of 27.22 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh DKK1 is approximately 42.9 kDa due to glycosylation.
• Protein Length: Met 2-His 266
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• Purity: > 90 % as determined by SDS-PAGE
• 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.
