Active Recombinant Human FGF19, Fc-tagged

• Cat.No.: FGF19-252H
• Product Overview: Recombinant Human FGF19(O95750-1)(Leu 25 - Lys 216), fused to Fc Tag, is expressed from human 293 cells (HEK293).

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• Protein Length: Leu 25 - Lys 216
• Form: Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Loaded Human FGF19, Fc Tag on Protein A Biosensor, can bind Human FGF R4, His Tag with an affinity constant of 1 μM as determined in BLI assay (ForteBio Octet Red96e).
• Molecular Mass: The protein has a calculated MW of 47.9 kDa. The protein migrates as 50-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >90% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage at:
  -20 centigrade to -70 centigrade for 12 months in lyophilized state;
  -70 centigrade for 3 months under sterile conditions after reconstitution.
• 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.
