Empowering science to create the technologies of the future

As leaders in protein innovation, approximately 30% of our catalog is formed of unique products including a tag-free thermostable FGF-2 (FGF2-G3), the first animal-free TGF-β1 for chemically defined stem cell media, and animal-free HGF (NK1).

We have developed a portfolio of stable, tag-free growth factors for use in the most popular pluripotency media recipes, and we provide pioneering growth factor forms for scaling organoid cultures.

Our product range spans a wide range of applications including hepatocyte, cardiac, and neural differentiation, all aimed at increasing reproducibility in your research. We actively support and innovate for emerging fields such as cellular agriculture, regenerative medicine, synthetic hydrogels, organ-on-a-chip, and bioprinting.

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.”

Prof Stephen O'Rahilly, University of Cambridge, UK
