Animal-free manufacture statement
Animal-free (AOF / ADCF) manufacture
Animal-free, animal–derived component free (ADCF), animal-origin free (AOF) and xeno-free mean different things to different manufacturers. Find out more about our manufacture process and the steps we take to ensure every stage is defined and controlled to provide an animal-free product.
We are always happy to help and answer any questions you have about specific products, processes and our animal-free ethos. Just email proteins@qkine.com or fill in our contact form.
Qkine proteins at a glance
What is the difference between animal-origin free (AOF) and animal-derived component free (ADCF)?
quick guide: AOF or ADCF? | AOF | ADCF |
---|---|---|
raw materials used directly in the product or as a starting material (e.g. E.coli growth media) are not derived from animal or human tissue, cells or body fluids | ✔ | ✔ |
raw materials used directly in the product or as a starting material do not contain animal or human tissue, cells, or body fluids at any stage of their manufacture process | ✔ | ✔ |
consumables used within the Qkine production process (e.g. filters) are not derived from animal or human tissue, cells or body fluids and no animal or human tissue, cells or body fluids are used at any stage of their manufacture process. | ✔ | ✗ |
Animal-free status certificates
Animal-free certificates, certificates of origin (manufacture details) certificates of analysis (quality and bioactivity information) and MSDS are available for all products – please request them here.
Manufacture process control
As part of our ongoing commitment to quality in every aspect of the company, animal-free 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-free.
Every stage of Qkine’s animal-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.
Every component used during the manufacture of our products is assessed by our quality team.
