|Description||The FGF family plays central roles during prenatal development and postnatal growth and regeneration of a variety of tissues, by promoting cellular proliferation and differentiation. FGF-19, a member of the FGF family, is a high affinity heparin dependent ligand for FGFR4. FGF-19 is expressed during the brain development and embryogenesis. Recombinant human FGF-19 is a 21.8 kDa protein containing 195 amino acid residues.|
|BiologicalActivity||Determined by a cell proliferation assay using balb/c 3T3 cells. The expected ED50 for this effect is 100-150 ng/ml.|
|Authenticity||Verified by N-terminal and Mass Spectrometry analyses (when applicable).|
|Endotoxin||Endotoxin level is <0.1 ng/ µg of protein (<1EU/ µg).|
|Protein Content||Verified by UV Spectroscopy and/or SDS-PAGE gel.|
|Precautions||Recombinant Human FGF-19 is for research use only and not for use in diagnostic or therapeutic procedures.|
