Is sr-Dog Polypeptide-4 vegan?

sr-Dog Polypeptide-4 is a recombinant single-chain protein produced by fermentation of genetically modified E. coli. The synthetic gene is designed to be identical to the gene encoding dog Insulin-Like Growth Factor, so although the sequence originates from an animal, the protein itself is produced synthetically by microbial fermentation without animal-derived material.

An ingredient is considered vegan if it contains no animal-derived components at any point in its production.
