High purity food grade growth factors for cultivated meat, fish, fat and dairy
Qkine is committed to manufacturing enhanced quality bioactive proteins to improve scientific outcomes and reproducibility. We provide an extensive portfolio of animal origin-free and carrier protein-free growth factors for the cultivated meat, fish, fat and dairy sectors.
Growth factors for cellular agriculture including cultivated meat, fish, fat and dairy
Cellular agriculture has the potential to transform food production and impact the health and well-being of future generations. Immediate priorities for cultivated meat and dairy process development include optimizing serum-free cell culture media to support cell expansion and maturation stages in bioreactor conditions.
Replacing animal-derived components, particularly fetal bovine serum (FBS), is essential for consistent performance, to remove the risk of contamination from viruses or prions and opens opportunities for fine-tuning of culture conditions.
Growth factors are critical components of cell culture media and provide a carefully orchestrated set of biochemical signals to control cell growth and fate. High purity, animal-free and optimized growth factors produced in an efficient microbial fermentation process provide the most reliable solution for cultivated meat and cellular agriculture.
We provide extensive quality analysis, documentation and support with novel food dossier preparation. Qkine food grade growth factors are manufactured in the UK under a food manufacturing HACCP regime. Full raw materials traceability, allergen analysis, CoO, CoA, beta-lactam-free and animal origin-free certification are available.

Species matched proteins
Regulators are advising using growth factors with protein sequences that are 100% homologous to the target species. Read about growth factor homology in commonly used growth factors.
Other species
Qkine do not currently have other species proteins in production, such as avian proteins. Please contact us if you’d be interested in high quality food grade proteins from other species.
