Rapid, reliable protein expression in your own lab.

Strain construction in K. phaffii is slow and unreliable. Most workflows test one sequence at a time. For protein engineers running design-build-test cycles, this is the bottleneck that decides how fast you can iterate.

nsure replaces conventional transformation and selection methods with a proprietary platform engineered for speed and throughput. You get:

• Sequence to expressing strain in as little as a week
• Library construction and screening in K. phaffii, for the first time
• Hundreds to thousands of sequences per run, where current methods test one

Want to screen larger libraries than your lab can run? Our pooled library screening service, launching September 2026, ranks candidates by manufacturability under production-representative conditions. It pairs naturally with libraries built using nsure.

The beta cohort gives you early access to the nsure platform in exchange for feedback that shapes the product. Beta testers receive technical support directly from the Change Bio team.
