Recombinant Human FSTL1 protein, His-tagged

• Cat.No.: FSTL1-714H
• Product Overview: Recombinant Human FSTL1 (Glu21-Ile308) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Description: Follistatin-related protein 1 (FSTL1) is also known as Follistatin-like protein 1 (FRP). FSTL1 is a secreted protein that contains two EF-hand domains, one follistatin-like domain, one Kazal-like domain and one VWFC domain. FSTL1 is overexpressed in synovial tissues from rheumatoid arthritis. Follistatin-like protein 1/FSTL1 may modulate the action of some growth factors on cell proliferation and differentiation. FSTL1 binds heparin.
• Source: HEK293
• Species: Human
• Tag: His
• Predicted N Terminal: Glu21
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4, 10% trehalose.
• Molecular Mass: The protein has a calculated MW of 32.7 kDa. The protein migrates as 35-50 kDa under reducing (R) condition (SDS-PAGE) due to differtent glycosylation.
• Protein length: Glu21-Ile308
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% 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 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.
