TSE/BSE declaration: The note for guidance EMA/410/01 Rev. 3 of the EC considers the
requirements of raw materials used for human and veterinary medicinal products. The document
introduces risk assessment into the regulatory compliance process for products derived from
TSE/BSE-relevant animal species.
We certify that this product is manufactured without the use of raw materials of animal or human
origin.
IPTG is of vegetable origin, produced by fermentation. During processing the product does not come
in contact with animal material. Therefore, the product does not fall under the scope of the above
mentioned guideline and is not concerned by the TSE/BSE issue.All packaging materials are not of
animal origin. The product does not come in contact with animal products during storage or
transportation. Depending on the quantity we either use PE-Flasks with original lids or PE-cans with
original lid with PE-bags inside or card boxes with PE-bags inside.
