Fibroblast Growth Factor-19 Human Recombinant ( FGF 19 Human )

Data sheet

Formulation

Filtered (0.2um) and lyophilized from 1mg/ml in 1xPBS, pH 7.4.

Solubility

It is recommended to reconstitute the lyophilized FGF-19 in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Description

FGF19 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 195 amino acids and having a molecular mass of 21.8 kDa.The FGF-19 is purified by proprietary chromatographic techniques.

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 19, FGF-19, FGF19.

Reagent Appearance

Filtered white lyophilized powder.

Stability

Lyophilized FGF-19 Human Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Fibroblast Growth Factor-19 should be stored at 4°C between 2-7 days and for future use below -18°C.For long
