    Human

    Expression system

    Escherichia coli

  • Affinity Tag

    His Tag (C-term)

    Buffer

    Lyophilized from a 0.2 µm filtered solution of PBS, pH 8.0.

  • Purity

    >98% as determined by SDS-PAGE analysis.

    Molecular weight

    The protein has a calculated MW of 20.35 kDa.
    The protein migrates as 25 kDa under reducing condition (SDS-PAGE analysis).

  • Activity

    Measure by its ability to induce proliferation in BaF3 cells transfected with human FGFRIIIc. The ED₅₀ for this effect is <0.4 μg/mL.

    Endotoxin level

    <0.1 EU per 1 μg of the protein by the LAL method.

  • Form

    Lyophilized

• Background

  • Background

    Fibroblast Growth Factors-21 (FGF-21) is a 22.3 kDa member of the fibroblast Growth Factors with 209 amino acid residues. FGF-21 is expressed from liver and cardiomyocytes. FGF-21 is a key protein that regulates important metabolic pathways, and modulates cellular function, metabolism, and senescence. It can stimulate glucose uptake in differentiated adipocytes via the induction of glucose transporter SLC2A1 /GLUT1 expression.
