An antibody recognises an epitope of a few residues. For a 16-residue peptide that may be most of the molecule or a fraction of it, and a fragment or a related sequence can bind. Oxidation of methionine or tryptophan within the epitope can abolish or reduce binding, so an assay may under-read oxidised peptide. Validation against a mass spectrometric method is rarely reported.
This is a general problem for short peptide hormones and not peculiar to MOTS-c.
Peptides in plasma are degraded by proteases unless inhibitors are added at collection, adsorb to plastic at low concentration, and can be masked by binding to plasma proteins. Haemolysis and lipaemia interfere with colorimetric readouts. Each study handles these differently and few report doing so in detail.
Freezer time and freeze-thaw cycles both reduce measured levels in reported stability tests.
Trust the direction of within-study comparisons — young versus old, before versus after exercise — more than the absolute values, and treat cross-study comparisons of concentration as uninformative until methods converge. This is a statement about the literature, not about the product.
MOTS-c is supplied by REVIVE LAB UAE for laboratory research use only, with identity by mass spectrometry and purity by HPLC for the batch. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
