Recombinant Rat Fibroblast Growth Factor-basic (rRtbFGF)

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.

Product Specifications

Source

Escherichia coli.

Field of Research

Neuroscience; Stem Cell & Developmental Biology

Endotoxin

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

Purity

>98% by SDS-PAGE and HPLC analyses.

Bioactivity

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.

Form

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

Molecular Weight

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

Storage Conditions

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.

Notes

For research use only.

Applications Notes

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.

Preservative

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