How it works
We produce recombinant cytokines by cell culture with proprietary processes — highly pure, active, tag- and carrier-free — and we make custom proteins to your specification.
1 · Tell us what you need
Pick from our catalog of 30+ cytokines, or describe the custom protein and quantity your program requires.
2 · Produce (catalog or custom)
For custom work, we take it from gene cloning through cell culture, serum-free media optimization, and mid-scale production up to 60L.
3 · Purify & verify
We purify to high activity and verify identity, purity, and endotoxin — with a standard specification of < 0.5 EU/mg by LAL.
4 · Ship active protein
You receive highly pure, active protein — tag- and carrier-free — with consistent lot-to-lot performance.

Frequently asked questions
Can you produce a cytokine to spec?
Yes — from gene cloning to purified, active protein in the vial, with custom process development available.
Do you sell research-grade reagents?
Yes. Browse flagship reagents in our shop, or contact us for bulk quantities and custom production.
What about endotoxin levels?
Each lot is assessed by the LAL assay, with a standard specification of < 0.5 EU/mg.
Are proteins tagged?
No — our biologics are available without any tag or carrier protein, so they won't interfere with your application.
