How to Read a MOTS-c Certificate of Analysis
A certificate of analysis (COA) is a report of test results for a specific lot of material.
Last reviewed and updated:
What should a COA contain?
- Identity
- Measured mass (e.g. by mass spectrometry) compared with the expected mass for the sequence.
- Purity
- Usually an HPLC percentage. Check the method and wavelength.
- Quantity
- Stated amount per vial, and how it was determined.
- Lot number
- Should match the number on your vial.
- Laboratory
- Who performed the testing (in-house or independent).
- Test date
- When the lot was analyzed.
- Methodology
- Instrument and method description.
Limitations of a COA
A COA is only as reliable as the lab and method behind it, applies only to the lot tested, and can be edited or misattributed. Independent verification is stronger than a supplier-issued document. Background: how materials are tested.

Lot-specific documentation, where available, is published by the supplier on its product page. We do not reproduce or vouch for test results here.
