Certified high quality food grade proteins with full traceability

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.

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 origin-free and optimized growth factors produced in an efficient microbial fermentation process currently provide the most reliable and reproducible solution for cultivated meat and cellular agriculture.

Growth factors and other recombinant proteins used at low concentrations in the cell culture media for cell maintenance, differentiation and/or maturation are considered food processing aids, or equivalent.

We provide extensive quality analysis, documentation and support with novel food dossier preparation. Qkine food grade growth factors are manufactured in the UK under an ISO 9001:2015 quality management system with food manufacturing HACCP regime in an allergen-free process. Additional documentation available for these produce include full raw materials traceability, protein allergen analysis, CoO, CoA, beta-lactam-free and animal origin-free certification.

Overview of Qkine high quality food grade growth factors and cytokines for cultivated meat, fat and dairy bioprocess development and optimization

  • Food grade proteins

Qkine food grade growth factors are manufactured in an ISO 9001:2015 certified facility in the UK with a food manufacturing HACCP regime established. All Qkine manufacturing is animal-orign free and a process allergen isolation system is in place.

Qkine high quality food grade products are intended solely for use as food processing aids, ex vivo cell manufacturing and research use. Not for direct human consumption, therapeutic or diagnostic use. The authorization of novel foods, including the use of growth factors as food processing aids, is regulated by regional government agencies. The use of our products as food processing aids in novel foods requires the end-user to obtain the necessary regulatory approvals.

  • High level of purity

Qkine have QC procedures which are targeted around removal of host cell proteins to ensure the highest level of purity in food grade growth factors.

We guarantee >98% protein purity due to assay limits, but we are confident that the true result is higher. To ensure purity, every lot is tested using mass spectrometry, ELISA and overloaded SDS-PAGE gels to ensure that there are no host contaminants, aggregates, or degradants.

  • Consistency & reliability enhanced

Utilizing animal origin-free recombinant proteins eliminates variations arising from trace animal components, promoting improved cell culture consistency. All our recombinant proteins mitigate the risk of contamination by mammalian pathogens, enhancing the reliability of cell products.

Qkine high quality food grade growth factors are manufactured under a HACCP regime to ensure the highest levels of food safety.

  • Excellent lot-to-lot consistency

All Qkine growth factors and cytokines have exceptional lot-to-lot consistency. Every lot is checked during a stringent QC process to ensure it has the same bioactivity as prior lots and to ensure reproducibility.

This minimizes the need for optimization in large scale or long term cultures, as consistent bioactivity is guaranteed from every lot.

  • Lowest endotoxin level

Current industry standards require endotoxin levels in growth factor lots to be less than 0.5 EU/ml, however the lower the better, and companies such as Qkine impose internal standards of <0.1 EU per µg protein.

  • Cost-effectiveness & scalability

Animal origin-free manufacturing offers greater supply chain stability and contributes to higher lot-to-lot consistency and reproducibility. This ensures that researchers can scale up production relying on consistent quality, reducing the need for extensive quality control measures and optimizing resource utilization.

High quality food grade manufacturing process control

As part of our ongoing commitment to quality in every aspect of the company, food grade protein production is taken into consideration from the very earliest planning stages of design and development. Before being incorporated into a procedure, newly-sourced materials must be reviewed and approved by our Quality team.

We continuously work with our suppliers to confirm and certify that the chemical components used within the manufacture of Qkine products are derived from non-animal and non-human sources and that the processes and components used in their own manufacture are animal origin-free.

ISO9001:2015 certified mark of trust with certificate number FS 747253

Every stage of the Qkine animal origin-free protein manufacturing employs Standard Operating Procedures (SOPs). SOPs are fundamental to assure consistency from lot to lot and guarantee the highest quality of products.

Qkine is ISO 9001:2015 certified for development, manufacture, and supply of proteins and related products, in addition our food grade proteins are manufactured under a HACCP regime.

Every component used during the manufacture of our products is assessed by our Quality team.

Animal free manufacturing process
  • DNA is transformed into competent bacterial cells which are generated using animal-free media
  • Fermentation processes follow approved SOPs
  • Raw materials and labware are animal-free* (see below)
  • All raw materials are traceable through batch records
  • All batches of bacteria are grown in animal-free media
  • Dedicated animal-free fermentors are employed
  • Equipment cleaning procedures have been validated
  • Purification processes follow approved SOPs
  • Dedicated animal-free columns are used* (see below)
  • Column cleaning procedures have been validated specifically for animal-free manufacturing
  • All labware which comes in contact with the product is animal-free* (see below)
  • Bulk purified proteins are filtered using certified animal-free filters
  • Line clearance procedures ensure all relevant areas are cleared of materials from the previous operation before filling commences
  • Lyophilization is conducted in a dedicated animal-free equipment

Any raw materials that are manufactured by fermentation, are considered animal-derived component free if no high or medium infectivity tissues are contained in the culture medium, as specified by the WHO Tables on Tissue Infectivity Distribution in Transmissible Spongiform Encephalopathies WHO/EMP/QSM/2010.1.

Although plastics themselves are produced from synthetic sources, additives manufactured from bovine tallow are often employed during the manufacture process to improve material properties and to aid in the processing of raw polymers. All plastics used directly within the Qkine manufacturing process are certified in compliance with the European “Note for guidance on minimizing the risk of transmitting animal spongiform encephalopathy agents via human and veterinary products (EMA/410/01-Rev 3)”.

All purification matrix are animal-free.
