Availability:

PODS™ Human FGF-7 crystals provide a depot of proteins which are steadily secreted. It has been estimated that the biological activity of 50 million PODS™ crystals generates the same peak dose as 3.3 µg of standard recombinant protein. However, at 5 days following the start of seeding the PODS™ crystals, there are more than 50% of these peak levels still present in the culture system. Ultimately, the amount of PODS™ crystals that is optimal for a particular experiment should be determined empirically, using 50 million PODS™ crystals equivalence to 3.3 µg of standard growth factor is a good starting point. To control for cross-reactivity with cells or as a negative control, we recommend using PODS™ growth factors alongside PODS™ Empty crystals, as the latter do not contain or release cargo protein.

Applications:

PODS™ protein crystals may be reconstituted at 200 million PODS™/ml in water. 20% glucose has a buoyant density closer to PODS™ protein crystals and can be useful for aliquoting. PODS™ protein crystals are highly stable when stored in aqueous solution (pH

Additional Information:
SOURCE: Spodoptera frugiperda (Sf9) cell culture; LENGTH: 208 aa; STRUCTURE: Monomer; FORMAT: lyophilized; ENDOTOXIN LEVEL: <0.06 EU/ml as measured by gel clot LAL assay; BACKGROUND: Fibroblast Growth Factor 7 (FGF-7), also known as Keratinocyte Growth Factor (KGF), is a potent mitogen that regulates epithelial cell migration and differentiation. FGF-7 is produced by mesenchymal cells and binds in high affinity to a splice variant of FGF receptor 2 (FGFR2-IIIb). The mitogenic activity of FGF-7 acts predominantly on keratinocytes, but not on fibroblast or endothelial cells. FGF-7 expression is upregulated after acute and chronic injury, suggesting that FGF-7 functions during the healing of injured epithelial cells. FGF-7 also induces the formation of the apical ectoderm ridge during limb development.
