SS-31 Handling Guide: Common Mistakes to Avoid
Most handling advice for research peptides is written generically. The practices below are the ones that specifically matter for SS-31 — including the mistakes it is unusually easy to make with this compound.
Overview
Low-bind tubes and buffers at low strengths; aliquot and refrigerate.
What SS-31 actually is
A tiny four-part peptide that homes in on the powerhouse of the cell, sticking to a lipid (cardiolipin) found only in the inner mitochondrial membrane. Studied around cellular energy, oxidative stress, and aging. Also called Elamipretide.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Bench practices for SS-31
- Reach room temperature before opening.
- Use low-bind labware and buffers at low working concentrations to limit adsorption of the cationic peptide.
- Aliquot and refrigerate.
The chemistry behind these practices
- Adsorptive loss to plasticware from the cationic charge — the main practical concern.
- Slow C-terminal amide hydrolysis over long storage.
