Qkine manufactures high-purity, animal-free growth factors, cytokines and other complex proteins.

Based on the Cambridge Science Park, we combine proprietary protein production processes developed at the University of Cambridge with protein engineering techniques to develop unique products that tackle fundamental biological and scale-up challenges for the fast-growing stem cell, organoid, regenerative medicine and cellular agriculture sectors.
Qkine has an active R&D pipeline, with a continually expanding product range. Unique products available from Qkine include tag-free thermostable FGF-2 (FGF2-G3), the first animal-free TGF-β1 for chemically defined stem cell media, and animal-free HGF (NK1).

Customer testimonials

“Our lab has been using FGF2 and activin A from Qkine in stem cell cultures for many months now.  Our epiblast stem cells and trophoblast stem cells never looked better.  Qkine has provided us with exceptional customer service and most importantly top-quality, affordable growth factors.  We will be definitely using their products in the future.”

Prof Jan Zylicz, Novo Nordisk Foundation, University of Copenhagen

“We have used GDF15 from Qkine in cellular experiments and in vivo and it performs very well.  Qkine staff are communicative and efficient and delivery times are excellent.”
