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

Our EntoEngine™ platform produces bioactive growth factors and other recombinant proteins more sustainably and cost efficiently than traditional expression systems.


FGF2 (Recombinant Bovine) Enriched Growth Media Supplement.


Transferrin (Recombinant Bovine) Enriched Growth Media Supplement.


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

Let's talk about 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 desperately 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.

And it doesn’t stop there…
