Purity

Greater than 90.0% as determined by SDS-PAGE.

Description

Fibroblast Growth Factor -21 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 202 amino acids (29-209) and having a molecular mass of 21.6 kDa (molecular weight on SDS-PAGE will appear higher). The FGF-21 is

Protein Background

The FGFs are a family of more than 20 small (~1726 kDa) secreted peptides. The initial characterization of these proteins focused on their ability to stimulate fibroblast proliferation. This mitogenic activity was mediated through FGF receptors (FGFRs) 1,

Expression host

Escherichia Coli.

Synonyms

Fibroblast growth factor 21, FGF-21.

Reagent Appearance

Sterile Filtered colorless clear solution.

Stability

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please avoid freeze thaw cycles.
