MOTS-c in McGill — Mitochondrial Peptide Research Guide
MOTS-c research guide for McGill. Mitochondria-derived peptide studied for metabolism and longevity — covers mechanism, purity standards, and sourcing quality MOTS-c.
For anyone in McGill looking to source MOTS-c, the first thing to know is that this compound is available only through an online research supply market. This matters because MOTS-c quality varies dramatically across the market — from analytically confirmed high-purity product to mislabeled or underdosed compounds — and the vendor controls every quality variable. Separating quality MOTS-c from the rest of the market depends on three things: an HPLC chromatogram confirming ≥98% purity, mass spec data verifying the correct molecular weight, and a batch-specific endotoxin panel. This guide gives McGill researchers the methodology to verify sourcing options methodically and source verified-quality MOTS-c with confidence.
What Studies Say About MOTS-c
MOTS-c is a recently characterized mitochondrial-derived peptide (MDP) encoded within the mitochondrial 12S rRNA gene — a mechanistically novel finding that challenged the assumption that mitochondrial genes only encode components of the respiratory chain. MOTS-c has been shown to activate AMPK, a master metabolic regulator, and to improve insulin sensitivity in mouse models. Its role as a mitochondria-to-nucleus communicator positions it at the intersection of metabolic health and aging biology. For McGill researchers in metabolic biology or mitochondrial research, MOTS-c in this class represents an emerging area with strong mechanistic grounding and growing experimental infrastructure.
How to Source MOTS-c — Vendor Guide
Before assessing any particular supplier, understand what genuine quality documentation contains — so you can identify whether a supplier meets the standard. Mass spectrometry in the COA confirms that the main HPLC peak is actually MOTS-c and not a structurally similar impurity — HPLC purity alone does not confirm what the compound actually is. Warning signs in MOTS-c vendor evaluation: prices significantly below market average, vague sourcing information, no community presence, and COAs that lack endotoxin data. Bacteriostatic water is the appropriate reconstitution medium for MOTS-c — it contains 0.9% benzyl alcohol that prevents microbial contamination and extends reconstituted shelf life to approximately one month when stored at 2-8°C.

COA-verified · International tracking · Research grade
Research compound status for MOTS-c means risk characterisation relies on animal studies, in-vitro work, and limited human observations — rather than the controlled trials that generate pharmaceutical safety profiles. Storage requirements for MOTS-c: lyophilised powder at minus 20°C, reconstituted solution refrigerated at 2-8°C and used within 30 days; reconstitute only with bac water. Endotoxin testing in the MOTS-c COA is non-negotiable — gram-negative bacterial endotoxins can trigger severe inflammatory responses at very low concentrations, and no pricing advantage justifies skipping this verification. The research literature on MOTS-c should be read critically before planning any study — study approaches, dose levels, and measured endpoints vary significantly and not all findings translate directly.
Frequently Asked Questions
What is bacteriostatic water and why is it used?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative. It inhibits bacterial growth in the vial, allowing multi-use over 30 days when kept refrigerated. It is the standard reconstitution medium for research peptides. Do not use tap water, saline, or plain sterile water for multi-use reconstitution.
What is a Certificate of Analysis (COA) for research peptides?
A COA is a quality document from a third-party analytical laboratory showing the results of testing for a specific product batch. For research peptides, it should include HPLC purity, mass spectrometry identity confirmation, bacterial endotoxin levels, and a residual solvent panel. The batch number should match your specific vial.
How do I reconstitute a lyophilized peptide?
Add bacteriostatic water slowly to the vial, directing it against the side wall rather than directly onto the lyophilized cake. Use a standard concentration appropriate for your dosing (e.g., 2mL bac water per 5mg vial = 2.5mg/mL). Gently swirl — never shake — to dissolve. Store reconstituted peptide at 2-8°C.
What purity should research peptides be?
Research-grade peptides should be ≥98% pure as confirmed by HPLC chromatography. Some vendors offer 99%+ purity for applications requiring higher specification material. Purity below 95% is generally considered inadequate for reliable research use.
Are research peptides legal?
Research peptides are generally legal to purchase and possess for research purposes in most countries. They are not approved pharmaceuticals, not scheduled controlled substances (in most jurisdictions), and importable for legitimate research use. Regulatory status varies by country and evolves over time — verify current status in your jurisdiction.
