Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Packaging, Storage & Formulations

Storage
Store at -20 to -70C as supplied. After reconstitution, store at 2 to 8C for 1 month and at -20 to -70C for long term storage. Avoid repeated freeze-thaw cycles.
Buffer
Lyophilized from a sterile (0.2 micron) filtered aqueous solution containing 20 mM NaP, 0.5 M NaCl, pH 7.5
Preservative
No Preservative
Concentration
LYOPH
Purity
>90%, by SDS-PAGE
Reconstitution Instructions
Sterile water at 0.1 mg/mL. 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.

Notes

Lot Specific Information:
Given endotoxin and ED50 values are acceptance criteria standards. For lot specific values, please contact technical support.

Detailed Reconstitution:
Centrifuge vial before opening. Suspend the product by gently pipetting the recommended solution down the sides of the vial. DO NOT VORTEX. Allow several minutes for complete reconstitution. For prolonged storage, dilute to working aliquots.

Expiration Date:
12 months from date of receipt when stored at -20C to-80C as supplied. 1 month when stored at 4C after reconstituting as directed. 3 months when stored at -20C to -80C after reconstituting as directed.

Background

Keratinocyte Growth Factor (KGF, FGF-7, HBGF-7) is a member of the FGF family of 23 related mitogenic proteins. These proteins play a central role during embryonic development and postnatal growth and tissue repair, by promoting cellular proliferation and differentiation. KGF specifically stimulates epithelial cells and keratinocytes, it is the most potent growth factor identified thus far for skin keratinocytes. KGF takes part in the development of kidney and lung, angiogenesis and has a key role in wound healing following skin injuries. It shows considerable species cross-reactivity (mouse, monkey, porcine cells) as the other members of the FGF family.
