This recent publication in collaboration with Qkine focusses on the optimization of home-brew media for the maintenance of human induced pluripotent stem cells (hiPSCs), using Qkine growth factors to allow cost-effective, practical, and reproducible culture of hiPSCs. Qkine thermostable tag-free FGF2-G3 proteins were found to be highly bioactive, necessitating an 8-fold reduction in concentration for the short (145 aa) form of FGF2-G3 in the optimized media.

Qkine is pleased to announce that it has successfully been recertified with the international standard ISO 9001:2015 by the globally respected UKAS accredited BSI, giving enhanced confidence in the assessment of best practices. This standard shows our dedication to raising the standard of bioactive proteins through implementation of continual improvement, scientific innovation and exceptional scientific and customer support

Qkine is a company run by scientists, and the science is the focus of everything we do. Our theme at ISSCR this year was stress-free stem cell culture - exploring how suppliers of recombinant proteins can proactively improve the quality, availability and functionality of growth factors to generate experimental outcomes faster, easier and more efficiently.

Reflections on the dynamic ISSCR 2024 workshop on Standards for Human Stem Cell Use in Research including recommendations for growth factor supply chains for raw (ancillary materials) for cell therapy and ATMP manufacture.

Commercial sources of recombinant human GDF15 protein, in particular those purified from mammalian expression, are frequently contaminated with trace amounts of TGFβ and related proteins. These trace contaminants cause misleading experimental results due to the picomolar or even femtomolar EC50s of this family of cytokines.  Please be cautious with your source of recombinant GDF15 protein.

Specialist bioactive growth factor protein manufacturer Qkine today announced a new partnership with StemCultures, a life sciences company dedicated to developing innovative reagents that enhance the quality and efficiency of cell growth and differentiation in culture.

The manufacture of cell and gene therapy products and tissue-engineered regenerative medicine products often requires recombinant proteins such as growth factors and cytokines. These are classified as raw or ancillary materials ie. culture media components or reagents that are not intended to be included in the final product.

We've recently fully transitioned to an animal origin-free (AOF) manufacturing process for our recombinant proteins. This shift ensures the highest standards of safety, purity, and sustainability in bioproduction. By eliminating all animal-derived components, including heparin-based purification columns, we’re supporting ethical and cruelty-free biomanufacturing. Learn more about our journey to 100% AOF.

As part of our commitment to constantly improving growth factor quality and availability, we will introduce a modest price increase on January 1st 2024.

Qkine has appointed Thomas Scientific as a new US Distribution Partner, making it easier for stem cell scientists in the US to purchase the entire Qkine product portfolio.
