Product Specs

Introduction

Fibroblast Growth Factor-19 (FGF-19) is a member of the FGF family that participates in various physiological processes, including bile acid biosynthesis regulation and glucose metabolism. FGF-19 binds to fibroblast growth factor receptors (FGFRs), particularly FGFR4, and initiates downstream signaling cascades. This growth factor plays a crucial role in maintaining metabolic homeostasis and has been implicated in various diseases.

Product Science Overview

Structure and Expression

FGF19 is a protein encoded by the FGF19 gene, located on chromosome 11q13.3 in humans . The protein consists of 216 amino acids and contains a signal sequence and two conserved cysteine residues . It is expressed in fetal brain tissue but not in adult brain tissue . The human recombinant version of FGF19 is often produced in HEK 293 cells, a human embryonic kidney cell line, to ensure proper folding and post-translational modifications .

Biological Functions

FGF19 plays a crucial role in regulating carbohydrate, lipid, and bile acid metabolism . It acts as a hormone-like protein that can stimulate hepatic protein and glycogen synthesis without inducing lipogenesis . The effects of FGF19 are mediated through the mitogen-activated protein kinase (MAPK) signaling pathway, which activates components of the protein translation machinery and stimulates glycogen synthase activity .

Clinical and Research Applications

Recombinant human FGF19 is used in various research applications, including:

  • Cell Culture: It is used to study cell proliferation and differentiation.
  • Functional Assays: It helps in understanding the biological activities and pathways involving FGF19.
  • SDS-PAGE and HPLC: These techniques are used to analyze the purity and molecular weight of the protein .
Production and Purity

The recombinant human FGF19 protein produced in HEK 293 cells is highly purified, with a purity level of ≥95% as determined by SDS-PAGE and HPLC . The endotoxin level is kept very low (≤0.005 EU/µg) to ensure its suitability for various biological assays .

Storage and Handling

The lyophilized form of recombinant human FGF19 should be stored at room temperature and reconstituted with phosphate-buffered saline (PBS) before use . Once reconstituted, it can be aliquoted and stored at -80°C for long-term storage or at +4°C for short-term use . It is important to avoid repeated freeze-thaw cycles to maintain the protein’s stability and activity .

Safety and Precautions

As an active protein, FGF19 can elicit biological responses in vivo, so it should be handled with caution . Researchers should follow appropriate safety guidelines and protocols when working with this protein.

In summary, Fibroblast Growth Factor-19 (Human Recombinant, HEK) is a valuable tool in scientific research, offering insights into various biological processes and potential therapeutic applications. Its high purity and biological activity make it suitable for a wide range of experimental studies.
