We use fruit flies to make Earth's most sustainable recombinant proteins.


Transferrin (Recombinant Bovine) Enriched Growth Media Supplement.


Fibroblast Growth Factor 2. Recombinant Bovine (>95% purity).


FGF2 (Recombinant Bovine) Enriched Growth Media Supplement.

Our EntoEngine™ platform produces serum-free, bioactive growth factors and other recombinant proteins more sustainably than traditional expression systems.

The Big Picture

The old way of producing recombinant proteins comes with an enormous environmental price tag.

With a looming climate crisis and rising demand for growth factors and proteins, the world needs a new paradigm in recombinant protein production.

We're the first to harness the sustainability, scalability, and scientific elegance of fruit flies to manufacture cost-effective proteins. The EntoEngine™ is taking a big bite out of energy use, waste, and CO2 emissions.
