Source:

Escherichia coli.

Molecular Weight:

Approximately 16.3 kDa, a single non-glycosylated polypeptide chain containing 145 amino acids.

Purity:

>98% by SDS-PAGE and HPLC analyses.

Biological activity:

Fully biologically active when compared to standard. The ED50 as determined by the dose-dependent stimulation of thymidine uptake by 3T3 cells is ≤ 0.2 ng/ml ,corresponding to a specific activity of ≥5 x 106 units/mg.

Endotoxin:

Less than 1EU/mg of rRabFGF as determined by LAL method.

Formulation:

Lyophilized from a 0.2mm filtered solution in PBS, pH 7.4.

Background:

FGF-basic is one of 23 known members of the FGF family. Proteins of this family play a central role during prenatal development and postnatal growth and regeneration of a variety of tissues, by promoting cellular proliferation and differentiation. FGF-basic is a non-glycosylated heparin binding growth factor that is expressed in the brain, pituitary, kidney, retina, bone, testis, adrenal gland liver, monocytes, epithelial cells and endothelial cells. FGF-basic signals through FGFR 1b, 1c, 2c, 3c and 4.

Usage:

This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.

Physical Appearance:

Sterile Filtered White lyophilized (freeze-dried) powder.

Reconstitution:

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at <-20°C. Further dilutions should be made in appropriate buffered solutions.

Storage:

This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
