About Qkine

Based at Murdoch House in Cambridge, Qkine manufactures high-purity, animal-free growth factors, cytokines, and other complex proteins for life science applications including stem cell and organoid culture. Qkine combines proprietary production processes with protein engineering technology to tackle fundamental biological, quality, and scale-up challenges.

Our goal is to provide the highest purity, bioactive proteins for research and bio-manufacturing to best support our customers and maximize the impact of their science.

Qkine is an ISO 9001:2015 certified company with an established global distribution network. With a robust manufacturing process, we can support scale-up and commercial manufacturing by offering lot reservations, bulk orders, custom vialling, and custom QA.

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.

We offer free worldwide shipping on all orders. You can buy growth factors direct from our website or through our knowledgeable distribution partners.
