Overview

A mitochondria-targeted research peptide.

SS-31, also known as elamipretide, is a synthetic, cell-permeable tetrapeptide studied for its selective interaction with cardiolipin, a phospholipid on the inner mitochondrial membrane essential to the electron transport chain. Rather than acting on a receptor, SS-31 concentrates directly at the mitochondrial membrane, making it a distinctive tool in bioenergetics research.

Suria's SS-31 is synthesized to high purity and independently verified prior to release, supporting consistent, reproducible results across mitochondrial function and oxidative stress research models.

Frequently Asked Questions

Good to know before you order.

How is it shipped?
Orders are packaged with care and shipped using protective, secure methods designed to help each vial arrive in excellent condition.
How should it be stored?
Store lyophilized vials as specified above, away from light and moisture. Once reconstituted, store at 2–8°C and use within your protocol's recommended window.
Is this for human consumption?
No. SS-31 is sold strictly for laboratory and scientific research use. It is not intended for human or veterinary use, and is not a drug, dietary supplement, or food.
Why does purity matter?
Purity directly affects the reliability of research outcomes. Available third-party analytical documentation can be reviewed for applicable batches through Suria's Batch Documentation system.
