Active Recombinant Human DKK4 Protein, His-tagged

• Cat.No.: DKK4-681H
• Product Overview: Recombinant Human DKK4 (Accession # NP_055235) Leu19-Leu224, fused with a C-terminal 10-His tag, was produced in Mouse myeloma cell line, NS0-derived.

Specification

• Species: Human
• Source: Mammalian Cells
• Tag: His
• Protein Length: Leu19-Leu224
• Predicted N Terminal: Leu19
• Form: Lyophilized from a 0.2 µm filtered solution in Tris-Citrate and NaCl with BSA as a carrier protein.
• Bio-activity: Measured by its ability to inhibit proliferation of HeLa human cervical epithelial carcinoma cells. Hsieh, S.Y. et al. (2004) Oncogene 23:9183.The ED50 for this effect is typically 1 - 5 µg/mL. Optimal concentrations should be determined by each laboratory for each application.
