DescriptionFibroblast Growth Factor 5 (FGF-5) is a secreted heparin-binding growth factor that binds to FGF receptors FGFR1 and FGFR2. FGF-5 is expressed in the mesenchyme, skeletal muscles, central nervous system, and hair follicles to promote cell differentiation and proliferation. FGF-5 functions as a regulatory factor during hair elongation and skeletal muscle development.
Activity AssayHuman FGF-5 is fully biologically active when compared to standard. The activity is determined by the dose-dependent induced proliferation of NR6R-3T3 cells with 1 µg heparin and it is typically less than 10 ng/ml. This corresponds to an expected specific activity of 1.0 x 105 units/mg.

|Molecular Weight||27.7 kDa|
|Purity||≥95% determined by reducing and non-reducing SDS-PAGE|
|Endotoxin Level||≤1.00 EU/μg as measured by kinetic LAL|
|Formulation||Lyophilized from a sterile (0.2 micron) filtered aqueous solution containing 10 mM sodium phosphate, 100 mM sodium chloride, pH 7.5|
|Reconstitution||Centrifuge vial before opening. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile water at 0.1 mg/ml, which can be further diluted into other aqueous solutions. If a precipitate is observed, centrifuge the solution thoroughly and use only the soluble fraction (removing it from the precipitate). A 10% overfill has been added to compensate for any loss of protein in the precipitate.|
|Stability and Storage||
12 months from date of receipt when stored at -20°C to -80°C as supplied. 1 month when stored at 4°C after reconstituting as directed. 3 months when stored at -20°C to -80°C after reconstituting as directed.
