Scope of this spotlight
This page consolidates molecular characteristics and laboratory handling notes for MOTS-c research material. It intentionally omits proposed research applications, dosing, administration routes, and outcome claims.
- MRWQEMGYIFYPRKLR
- C101H152N28O22S2 (illustrative free base framing — confirm salt form on COA)
- ~2174.6 Da (verify lot-specific MS / calculation)
- White to off-white lyophilized powder (typical)
- Often approached in aqueous systems; confirm solvent system against COA / method needs
- Sealed, protected from moisture; commonly −20°C for long-term holds
- Define validated hold time in your SOP; minimize freeze–thaw cycles
Identity anchors
Laboratory identity checks typically combine:
- Sequence / formula documentation from the supplier
- Observed mass consistent with the expected Dalton value
- Chromatographic purity consistent with the COA method
-0.05
MOTS-c (illustrative): Within typical identity window
Stability & handling characteristics
Like many lyophilized peptides, MOTS-c research lots are generally more stable in the dry, sealed state than after reconstitution. Practical laboratory controls include:
- Limit light and humidity exposure when vials are open
- Avoid aggressive mechanical shear during dissolution
- Document storage location, temperature logger IDs, and open dates
| Condition | Max recommended duration | Stability notes | Status |
|---|---|---|---|
| −20°C, sealed | Per COA dating | Preferred archive condition for dry cake when validated by the supplier statement. | Recommended |
| 2–8°C, sealed | Short staging | Interim refrigeration may be used when SOPs allow brief staging before reconstitution. | Limited |
| Ambient, open vial | Avoid prolonged | Humidity and contamination risk rise once the seal is broken. | Not preferred |

Expansion note
Additional compound spotlights (BPC-157, TB-500, and others from the catalog) should reuse this template: sequence/formula, mass, appearance, solubility, stability framing, and storage handling — sourced from primary literature and analytical documentation, not competitor blog copy.
