Synonyms:
FGF-5, Heparin-binding growth factor 5, HBGF-5, Smag-82
Description:
Fibroblast growth factor 5 is a secreted heparin-binding growth factor that binds to FGF
receptors 1 and 2 (FGFR1 and FGFR2). FGF-5 is expressed in the mesenchyme,
skeletal muscles, central nervous system, and hair follicles and plays an important role in
the regulation of cell proliferation and cell differentiation. Required for normal regulation
of the hair growth cycle and skeletal muscle development. Functions as an inhibitor of
hair elongation by promoting progression from anagen, the growth phase of the hair
follicle, into catagen the apoptosis-induced regression phase.

Reconstitution:
Centrifuge vial prior to 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 a concentration of 0.1 mg/mL, which can be further diluted into other aqueous solutions.
Storage/Stability:
Store as supplied at -20°C to -80°C for up to 1 year. Upon reconstitution, prepare working aliquots and store at -20°C to -80°C. It is recommended that a carrier protein such as 0.1% HSA or BSA is added for long term storage. Avoid repeated freeze-thaw cycles.
