The success of stem cell research depends on the development of optimal cell culture systems. Both expansion and differentiation of stem cells is highly reliant on growth factor and cytokine supplements, with the activity and purity of these recombinants being critical to successful research and clinical applications. Despite recognised limitations - E. coli and mammalian cells remain the dominant expression systems for commercial recombinant protein production. Although significant improvements in manufacture have been made, both systems present a risk of unwanted contamination from pathogens and endotoxins.     
     
AMSBIO now offer for recombinant growth factors and cytokines for system culture produced in plant based expression system utilizes barley seed that cut the risks associated with endotoxin, viral infection and other human pathogen infection.
