MOTS-c Research: Critical Quality Standards for Mitochondrial Peptide Studies

MOTS-c is a 16-amino-acid mitochondrial-derived peptide that requires ≥98% purity for meaningful research — lower purity grades introduce peptide fragments that can confound experimental outcomes. Here’s what your lab needs to know before starting MOTS-c research.

Verification Requirements

Every batch of research-grade MOTS-c should be accompanied by HPLC chromatogram (≥98% single peak), mass spectrometry (matching theoretical MW of 2174.7 Da), and amino acid analysis confirming the correct sequence. Labs should independently verify these documents or send samples for third-party testing before incorporating material into experimental protocols.

Storage and Handling

MOTS-c lyophilized powder is stable at -20°C for 12+ months when properly desiccated and protected from light. Once reconstituted, use within 48 hours at 4°C — MOTS-c is more stable than many research peptides but still degrades in solution over time.

FAQ

Q: What concentration of MOTS-c is appropriate for in vitro research?

A: Published research typically uses 10-100 μM concentrations for cell culture studies, with dose-response curves to establish appropriate ranges for specific cell lines. Always reference the most recent peer-reviewed literature for your specific experimental model.

Q: How do I verify MOTS-c identity independently?

A: Send a sample to an independent analytical lab (Janoshik, MZ Biolabs, or similar) for HPLC and MS analysis. This costs roughly $100-200 per test and provides unbiased verification of supplier claims.
