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.

Implementing animal-free recombinant proteins into stem cell supply chains

Most industries today are under pressure to switch to more ethical and sustainable animal-free alternatives, and now the trend is coming to stem cell labs. As stem cell applications accelerate towards the clinic, novel drug discovery platforms are rapidly scaled, and new transformative stem cell-based technologies such as cultured meat arise, there is [...]
