Analyst Comments

Lyophilized powder, black-cap vial, received sealed. MOTS-c was not found in the sample (detection limit about 0.1 mg per vial). The dashed trace is a MOTS-c reference run on the same method, marking where MOTS-c elutes. The only sample peak past the void is a small unidentified UV-absorbing component.
