Active Recombinant Human FSTL4 Protein, His-tagged

• Cat.No.: FSTL4-688H
• Product Overview: Recombinant Human FSTL4 (Accession # NP_055897) Trp23-Val842, fused with an N-terminal 7-His tag and Asn, was produced in Chinese Hamster Ovary cell line, CHO-derived.

Specification

• Species: Human
• Source: CHO
• Tag: His
• Protein Length: Trp23-Val842
• Predicted N Terminal: His
• Form: Lyophilized from a 0.2 µm filtered solution in PBS.
• Bio-activity: Measured by its ability to inhibit BMP-6-induced alkaline phosphatase production by MC3T3-E1 mouse preosteoblast cells.The ED50 for this effect is typically 2 - 10 µg/mL in the presence of 0.1 µg/mL of recombinant human BMP-6.
• Molecular Mass: Recombinant Human FSTL4, His-tagged has a calculated MW of 93.6 kDa. In SDS-PAGE migrates as 100 kDa, reducing conditions.
• Purity: >95%, by SDS-PAGE under reducing conditions and visualized by silver stain.
• Storage: Avoid repeated freeze-thaw cycles. No activity loss was observed after storage at: In lyophilized state for 1 year (4ºC); After reconstitution under sterile conditions for 3 months (-70ºC).
