Active Recombinant Human SFRP4 protein, His-tagged

• Cat.No.: SFRP4-864H
• Product Overview: Recombinant Human SFRP4 protein(NP_003005.2)(Met1-Val346), fused with His tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. 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 C3H10T 1/2 2A6 mouse embryonal fibroblast cells.The ED50 for this effect is typically 1-6 μg/mL in the presence of 20 ng/mL of Wnt3a.
• Molecular Mass: The recombinant human sFRP4 consists of 336 amino acids after removal of the signal peptide and has a predicted molecular mass of 39 kDa. In SDS-PAGE under reducing conditions, it migrates with an apparent molecular mass of 55-60 kDa due to glycosylation.
• Protein length: Met1-Val346
• Endotoxin: < 1.0 EU per μg of the 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°C before opening to recover the entire contents.
