Fibroblast Growth Factor-4 Human Recombinant ( FGF4 Human )

Data sheet

Formulation

The FGF4 protein was lyophilized with 2xPBS, pH 7.4.

Solubility

It is recommended to reconstitute the lyophilized FGF4 Human Recombinant 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 SDS-PAGE.

Description

FGF4 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 182 amino acids and having a molecular mass of 19.8kDa. The FGF4 is purified by proprietary chromatographic techniques.

Protein Background

FGF4 holds s comprehensive mitogenic and cell survival activities and takes part in a range of biological processes including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. FGF4 possess oncogenic transforming

Expression host

Escherichia Coli.

Synonyms

HBGF4, FGF-4, FGF4, KFGF, HSTF1.

Stability

Lyophilized FGF4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FGF-4 should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles.

Physical Appearence

Sterile Filtered White lyophilized (freeze-dried) powder.

Biological Activity

The ED50 as determined by the dose-dependent stimulation of thymidine uptake by BaF3 cells expressing FGF receptors is 0.5ng/ml, corresponding to a specific activity of > 2,000,000units/mg.
