How we scored it
Recombinant protein from the 20 standard amino acids via bacterial fermentation (Nerve Growth Factor Beta copy); synthesis leaves no mass = 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Produced by fermenting genetically modified E. coli expressing a synthetic gene copy of human Nerve Growth Factor Beta. No alternative route.
In plain English
A protein made by fermenting engineered bacteria that produce a copy of a natural human growth factor. Used in hair-conditioning and skin-protecting products.
CosIng definition: sh-Polypeptide-14 is a single chain synthetic human peptide, produced by fermentation in E. coli. The starting gene is a synthesized copy of the human gene which codes for Nerve Growth Factor Beta used as such or adapted to the production host. It contains a maximum of 241 amino acids which may contain disulfide bonds and/or glycosylation. The protein consists of the proper sequence of the 20 standard amino acids.
