We are the sole producer of active recombinant selenoproteins

And with our technology we could theoretically produce any of the 800+ natural selenoproteins yet identified in nature, or any synthetic selenocysteine-containing proteins on demand.

Our recombinant production system uses bacteria

Making the production cost lower compared to use of mammalian systems, and allows us to offer selenoproteins at competitive prices compared to selenoproteins purified from native sources.

Our edge-cutting technology results from 30+ years of extensive research at Karolinska Institutet in Stockholm, Sweden, now making selenoproteins available for academic research and the global Pharma and R&D sectors.

The use in our selenoprotein production technology of E. coli strains lacking RF1 and any endogenous use of TAG/UAG codons is enabled under a license agreement with Harvard College.
