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.
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.
We are proud to launch our Pioneering Protein range! A range of modified proteins have been carefully developed by world leading academic laboratories, licenced through Cambridge Enterprise, and then manufactured to our high purity and bioactivity standards, bringing together academic innovation with high level manufacturing purity. Folloistatin-resistant activin A (FRACTA) has been developed by our [...]
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 [...]
Hydrophobic or aromatic? Flexible or rigid? We've designed a handy (and free!) infographic of the amino acid chemical structures and side chain properties. Why not save a copy and hang it up in your lab?
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.
