Recombinant Human FGF7, His-tagged

"FGF7" Related Products.
Product Overview:
Recombinant Human FGF7 was produced in the endosperm tissue of barley grain (Hordeum vulgare).
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.
Barley grain (Hordeum vulgare)
Sterile filtered through a 0.2 μm filter. Lyophilized from PBS, pH 7.2
Recombinant human KGF was determined by its dose dependent effect on proliferation of 4MBr5 rhesus monkey epithelial cells. The ED50 for this effect is typically below 4 ng/ml corresponding to specific activity of >2.5 x 10e5 U/mg. Optimal concentration should be determined for specific applications and cell lines.
Molecular Mass:
Recombinant human KGF contains 164 amino acids and a 16 a.a. histidine-based tag for a total length of 180 a.a. and has a predicted molecular mass of 21.2 kDa including his-tag. As a result of glycosylation, the recombinant protein migrates as two bands with an apparent molecular mass of 26 and 28 kDa in SDS-PAGE.
Endotoxin level is less than 0.005ng per μg product (0.05EU/μg).
Greater than 95% by SDS-PAGE gel analysis.
The lyophilized protein, though stable at room temperature for 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.
Always centrifuge the vial before opening. It is recommended to reconstitute the lyophilized protein in sterile water to a concentration of no less than 100 μg/ml. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
