Recombinant Human FGF19 Protein (rp145934) - Protein Bioactivity
FGF19 is a member of the fibroblast growth factor (FGF) family. FGFs are heparin-binding growth factors with a core 120 amino acid (aa) FGF domain that allows for a common tertiary structure. In general, FGFs are expressed during embryonic development and in restricted adult tissues. Human FGF-19 cDNA predicts a 251 aa precursor protein with a 22 aa signal peptide and a 229 aa secreted mature protein with no potential N-linked glycosylation sites. FGF19-FGFR1 is one of paired transcripts mediating the dialogues between extraembryonic membrane and endometrium. A functional binding ELISA assay was conducted to detect the interaction of Recombinant Human FGF19 Protein (rp145934) and recombinant human FGFR1, the EC₅₀ for this effect is 0.16 μg/mL.

Recombinant Human FGF19 Protein (rp145934) - SDS-PAGE
3 μg/lane of Recombinant Human FGF19 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the band at 27.7 kDa under reducing conditions and 27.4 & 54.0 kDa under non-reducing conditions.
