Fibroblast Growth Factor-21 Rat Recombinant ( FGF 21 Rat )

Data sheet

Formulation

Lyophilized from a 0.2um filtered concentrated solution in 1PBS, pH 7.4.

Solubility

It is recommended to reconstitute the lyophilized FGF 21 Rat Recombinant 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

FGF 21 Rat Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 180 amino acids and having a molecular mass of 19.7kDa. The FGF 21 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 21, FGF-21.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized FGF 21 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FGF 21 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add

Biological Activity

Fully biologically active when compared to standard. The ED50 determined by a cell proliferation assay using murine NIH/3T3 cells is less than 700 ng/ml, corresponding to a specific activity of > 1.4 1000 IU/mg in the presence of 5ug/ml of rMuKlotho-beta
