Description
ISOkine® KGF (FGF-7) Human, Animal-Free Recombinant Protein is a high-purity, bioactive growth factor expressed in barley grain and provided as a lyophilized powder. The protein produced under ISO 9001:2015 conditions contains 163 amino acids and an N-terminal 6 amino acid histidine tag for a total length of 169 amino acids and has a predicted molecular mass of 19.7 kDa.
ISOkine® growth factors and cytokines are animal-free (AOF/ACF), serum-free, and void of antibiotics, endotoxins, viruses, and prions.
Summary
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.
Source
Expression Host: Produced in the endosperm tissue of barley grain (Hordeum vulgare) plants.
Manufacturer: ORF Genetics
Country of Origin: Iceland
Formulation
2xPBS pH 7.2, sterile filtered through 0.22 µm filter
Purity
Greater than 95% by SDS-PAGE gel analysis
Reconstitution
Always centrifuge the vial before opening. It is recommended to reconstitute the lyophilized protein in sterile phosphate-buffered saline to a concentration of no less than 100 µg/ml. For long-term storage of the reconstituted solution, it is recommended to add a carrier protein (0.1% HSA or BSA).
Stability
The lyophilized protein, though stable at room temperature for a few weeks, is best stored at -20°C. Reconstituted protein should be used immediately or stored in working aliquots at -20°C. Avoid repeated freeze-thaw cycles.
Biological Activity
Each batch of ISOkine® growth factors is tested for bioactivity and verified to have comparable activity to a commercial source. The bioactivity of ISOkine® recombinant human KGF is assayed by measuring its dose-dependent effect on the proliferation of 4MBr5 rhesus monkey epithelial cells. The ED50 for this effect using KGF is typically <60 ng/ml. Optimal concentration should be determined for specific applications and cell lines
Endotoxin Level
Endotoxin level is < 0.01 EU per μg of ISOkine® product by LAL method.
Pyrogen Free
Purified ISOkine® product carries no pyrogenic or pro-inflammatory contaminants, as assayed with monocyte activation test (MAT Assay) using Human 10-plex Cytokine Assay measuring IL-6, TNF-alpha, and IL-1 beta induction.
Usage
This product is intended for laboratory research use only. Not for use in diagnostic or therapeutic procedures. This product may not be used as a pharmaceutical or veterinary drug, agricultural product, or food additive.
Synonyms
Human KGF, Keratinocyte growth factor, Human FGF-7, Human FGF7, Fibroblast growth factor 7, Heparin-binding growth factor 7, HBGF-7.
