Why our SCB scientists think using insect cells (sf9) to express Ubiquitin is a good idea.

Behind every functional ubiquitin enzyme lies a careful choice: how and where it’s expressed.
Our scientists know that expression systems matter:

E. coli offers speed, but many ubiquitin enzymes misfold, aggregate, or form inclusion bodies.
Insect cells (like Sf9) provide a eukaryotic environment, enabling proper folding, post-translational modifications, and stability.

Equally important is the choice of purification tag (His, GST, or others) because ubiquitin-like proteins are small and easily misfolded if not handled properly.

By refining these details, SCB ensures that every enzyme we deliver is active, validated, and research-ready. It’s a subtle but critical part of our craft, turning complexity into reliability for scientists pushing the boundaries of ubiquitin research.
