PODS® Human FGF-20
PODS® TechnologyPODS® proteins are made using an insect cell expression system in which the active protein is co-expressed alongside polyhedrin carrier protein. Polyhedrin forms microcrystals within insect cells which specifically capture the active protein to form a co-crystal complex. The active protein is captured in its nascent, natively folded form with limited scope for proteolytic degradation. Consequently, excellent levels of bioactivity are observed. The PODS® co-crystals provide a sustained release mechanism and can be used to functionalize surfaces. For further details, please refer to the PODS® Technology page.
Product DescriptionThe product contains the polyhedrin protein co-crystalized with Human FGF-20. Fibroblast Growth Factor 20 (FGF-20) is a member of the fibroblast growth factor family, more specifically of the FGF-9 subfamily based on their structural and sequence similarities. It is expressed by a variety of cell types including fibroblasts, dopaminergic neurons, keratinocytes and epithelial cells. FGF-20, also regarded as a secreted neurotrophic factor, is involved in many biological processes, such as tumour growth, tissue repair, and embryonic development, specifically in the development of the central nervous system. It has shown to interact with FGF receptors 1c, 2c, 3b and 3c and 4c.
PODS® co-crystals provide a depot of proteins which are steadily secreted. It has been estimated that the biological activity of 50 million PODS® co-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® co-crystals, there are more than 50% of these peak levels still present in the culture system. Ultimately, the amount of PODS® co-crystals that is optimal for a particular experiment should be determined empirically. Based on previous data, we suggest using 50 million PODS® co-crystals in place of 3.3 µg of standard growth factor as a 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.
