ISOkine™ growth factors and cytokines are biorisk-free since they are produced in the endosperm of barley seeds. They are animal and serum-free, void of antibiotics, endotoxin-free, pyrogenic and pro-inflammatory-free, void of bacteria, viruses and prions and are eukaryotic folded and glycosylated. Their production is environmentally friendly and CO₂ neutral, as renewable, geothermal energy is used in their production. Furthermore, the biological activity typically is comparable or better than of other growth factors and cytokines on the market.
