MOTS-c is a compact 16-residue peptide, and confirming a synthetic lot matches its defined sequence is the analytical starting point for any research use, whether or not the underlying biology involves its mitochondrial genomic origin.
Reversed-phase HPLC
HPLC resolves the correctly synthesized 16-residue chain from truncated fragments and other synthesis-related byproducts, with purity read per understanding HPLC purity.
Mass spectrometry for identity
Mass spectrometry confirms the peptide's mass matches the sequence described in its chemistry article, closing a gap that HPLC retention time alone cannot — general background is in HPLC vs. mass spectrometry.
Why a synthetic reagent is not the same as the endogenous peptide
A certificate of analysis confirms that a purchased vial contains the correct synthetic sequence at a stated purity — it says nothing about the endogenous production, transport, or regulation MOTS-c undergoes in a cell, a distinction relevant to interpreting its AMPK-linked mechanism. Researchers should keep synthetic-reagent verification and endogenous-biology claims separate when reporting results.
