We are being incubated

We are happy to be accepted to S2B Launchpad business incubator by Tartu Science Park. Under supervision of two experienced mentors and loads of networking opportunities, we believe to boost our startup readiness.

Switcher Technology

Gearbox Biosciences has developed a robust switch that allows us to control bacterial growth with high precision. Our patent pending Switcher Technology is based on induced removal of origin of replication from bacterial chromosome. Switched cells do not divide but remain metabolically active, which enables to decouple protein production from cellular growth.

Switching significantly increases the protein productivity in bacterial cells because switched cells do not “waste” resources on growth but channel majority of them for product synthesis.  In lab environment a recombinant protein expression is upregulated 2 – 5 times without any other optimisation.

More detailed overview of our technology can be found from the preprint of our research publication
