Qkine and Enantis sign licensing deal for hyperstable FGF2-STAB®

Qkine and Enantis have concluded a global licensing deal for Enantis’s patented FGF2-STAB® technology. FGF2-STAB® is a hyperstable form of FGF-2 (bFGF), a core reagent for stem cell culture. FGF2-STAB (FGF2-G3) does not degrade in culture media for enhanced weekend-free stem cell culture media and advanced chemically defined systems, such as those needed in the cultured meat industry.

mouse LIF protein vs ESGRO?

There is no fundamental difference between ESGRO and recombinant mouse leukaemia inhibitor factor (mLIF) protein. Both can be used for the successful maintenance of mouse embryonic stem cell (ESC) pluripotency. 10E7 units of ESGRO is equivalent to 100 µg of pure protein. Thank you to Susanne van den Brink (postdoc in Anna Bigas lab, IMIM, Barcelona) and David Turner (University of Liverpool) for sharing their resuspension protocol to prepare ESLIF media.

Video: Growth factor purity and its implications for stem cell culture

Presentation by Luana Ferrara, Senior Protein Scientist Video script Slide 1: Introduction  Hello! My name is Luana Ferrara and I am a senior protein scientist at Qkine. In this short video, I’ll be presenting a comparative analysis of the purity of recombinant Activin A from different suppliers and highlighting why it's important to consider the biochemical quality of growth factors for your stem cell culture.   Slide 2: The role of [...]

Why quality is not just about purity – by Qkine founder Dr Marko Hyvönen

As a structural biologist, one will very quickly realise that protein not only needs to be pure, but it needs to be also homogeneous and the real proof of the protein’s quality is in its specific bioactivity. So,we clearly need different criteria for defining quality and that is what we do at Qkine.
