A designation from biomanufacturing, and why it attaches to this molecule

Published 26 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Animal-origin-free, or animal-component-free, means that no material of animal origin — serum, tissue extracts, animal-derived enzymes, media components from animal sources — was used in producing the protein, from the fermentation medium through purification to the final formulation. Regulators of biological medicines require manufacturers to minimise the risk of transmitting animal pathogens, especially prion diseases, and a supplement that goes into production media must therefore be documented as free of such inputs. IGF-1 LR3 made for that market carries this documentation; research-grade material may or may not.

What it covers

The expression host is bacterial, so the protein itself has no animal origin. The designation concerns everything else: the peptone or yeast extract in the fermentation broth, the enzymes used in any processing step, the stabilisers in the final product, and the equipment cleaning agents. Each is traced to a non-animal source and documented.

It is a supply-chain statement as much as a product statement.

Why it is required

The prion episode of the 1980s and 1990s, including the growth hormone cases described elsewhere on this site, made transmissible spongiform encephalopathy risk a regulatory priority. Any material entering the manufacture of an injectable biological must be assessed for it, and the simplest assessment is the absence of animal inputs.

The same logic drove the move from serum to defined media.

Research-grade material

The catalogue product is research-grade and its batch documentation states what was tested. Whether it carries an animal-origin-free statement is a matter for that documentation; this page explains what the statement would mean.

IGF-1 LR3 is supplied by REVIVE LAB UAE for laboratory research use only, with identity and purity documented for the batch. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
