The supply problem
Growth factors shouldn't be the bottleneck
Variability in purity and bioactivity forces re-validation and risks your results.
Serum and animal-component inputs raise contamination and supply-chain risk.
Conventional growth factors are expensive and hard to scale from research to production.

Why ORF
Consistent, animal-free, cost-effective
Consistent quality & supply
Greater than 95% purity, endotoxin-free, and batch-to-batch reproducibility. Validate once and scale with confidence, knowing every lot meets the same specification.
A fraction of the cost
Molecular farming economics let you scale from research to production without runaway reagent budgets. Cost-effective at every stage, from first experiment to commercial volume.
Biorisk-free, animal-free
Plant-produced and endotoxin-free by design. No animal-derived inputs means lower contamination risk and a simpler supply chain, from bench to process development.
25 years of doing this
Molecular farming since 2001, ISO 9001:2015 certified, and on the road to GMP. A supplier with the track record and quality systems you can build a process on.
By the numbers
A supply you can build a process on
Producing plant-based recombinant growth factors since 2001 under an ISO 9001 quality system. Research and cultivated-meat teams worldwide standardise on ORF Genetics for purity, consistency, and reliable scale.

How we make them
Grown in barley, purified for the bench
Molecular farming in barley
ORF's Orfeus barley-seed expression platform produces recombinant proteins at scale, providing a clean, animal-free production route free from serum or mammalian cell-culture inputs.
Endotoxin-free by design
A plant host carries no animal-derived contaminants. Every batch is endotoxin-free by design, reducing biorisk for sensitive cell-culture work where purity directly affects outcomes.
Powered by geothermal energy
ORF's greenhouse operations run on Iceland's geothermal grid, giving each batch a low carbon footprint and contributing to a more sustainable, resilient supply chain.
