Cambridge, UK and San Diego, CA, USA – Qkine, a leading recombinant protein manufacturer and Defined Bioscience, a leading cell culture media supplement supplier, are excited to announce a distribution agreement to support access to Defined Bioscience’s high-quality products outside of the US.
Defined Bioscience has set out to solve the scale bottleneck faced by cell culture scientists. Existing stem cell media and supplements are expensive, variable and difficult to scale. Animal-derived, poorly defined media components further compound these issues, adding to the expense and reducing reproducibility. Defined Bioscience’s cell culture media supplements are animal-free, fully defined, reproducible, and affordable.
Defined Bioscience’s animal-free media supplements are the perfect pairing for Qkine’s animal-free growth factors, cytokines and adhesion proteins. Both companies share the same customer-focused values, quality, transparency, and reproducibility, and strive to support the scientific community with the best tools for cell culture. Qkine’s decision to supply Defined Bioscience’s media supplements alongside our animal-free proteins to our customers and collaborators will further our goal to make available entirely animal-free, traceable and scalable workflows.
