MOTS-c is the name used for a 16-residue peptide identified from the mitochondrial 12S rRNA region. The supplied reports describe that peptide length and compare the samples with a qualified reference, but do not print the complete sequence.
What does the MOTS-c name identify?
Lee and colleagues introduced MOTS-c from a short open reading frame in the mitochondrial 12S rRNA region. The expanded name is mitochondrial open reading frame of the 12S rRNA type-c. Figure 1 gives the reference sequence MRWQEMGYIFYPRKLR. This sequence belongs to the published molecular reference; it is not printed in the supplied reports.Lee et al.

Both documents report an LC-HRMS comparison with a qualified reference. They are separate sample records with their own lots and results. Select the certificate for the relevant vial size and lot rather than carrying one report’s values into the other size.MOTS-c 10 mg report: MA-MOT-0021 (opens in a new tab)MOTS-c 20 mg report: MA-MOT-0022 (opens in a new tab)
Complete the reference specification
For a full structural comparison, request the reference sequence, terminal groups, any modifications and the chemical form associated with the certificate. The linked reports identify their reference-matching method but do not supply those fields in full.MOTS-c 10 mg report: MA-MOT-0021 (opens in a new tab)MOTS-c 20 mg report: MA-MOT-0022 (opens in a new tab)
Record a database identifier only when its represented structure has been matched to that specification. A catalogue name or residue count is a useful starting point, but neither substitutes for the missing reference details.MOTS-c 10 mg report: MA-MOT-0021 (opens in a new tab)MOTS-c 20 mg report: MA-MOT-0022 (opens in a new tab)
