What is SS-31?

SS-31 (also known as Elamipretide; previously designated MTP-131) is a synthetic research peptide supplied for controlled laboratory investigation. Researchers study this peptide in structured research focused on mitochondrial signaling, inner membrane interaction behavior, and oxidative stress related pathways within experimental models. Its defined peptide sequence allows laboratories to design repeatable studies under stable and standardized research conditions.

Because SS-31 represents a well characterized peptide sequence belonging to the Szeto-Schiller (SS) class of mitochondria-associated research peptides, researchers use it to explore how specific peptide structures interact within controlled research environments. This focused approach helps research teams examine signaling behavior, interaction patterns, and sequence specific responses while maintaining strong control over experimental variables. As a result, laboratories can collect clear and repeatable data across multiple study phases.

In laboratory settings, scientists handle SS-31 using standard peptide preparation and safety procedures. The peptide format supports accurate measurement and controlled use during experiments. Therefore, research teams can maintain stable testing conditions and focus on observation, documentation, and data analysis without unnecessary variation.

Researchers also value this peptide for its consistent composition and compatibility with structured research workflows. Its stability supports longer research timelines and helps reduce variability between experiments. This consistency allows laboratories to compare data across studies that examine similar peptide sequences or mitochondrial interaction models.

In addition, SS-31 supports research projects that require dependable materials for repeated testing cycles. Laboratories often rely on clearly defined peptide sequences when building structured research protocols, and this peptide fits well within those frameworks. Its predictable handling characteristics further support careful experimental planning and execution.

Ongoing scientific research continues to include SS-31 in peptide focused laboratory studies. Researchers use this peptide to support investigations into mitochondrial signaling behavior and controlled molecular interaction models. Its defined sequence, stable behavior, and suitability for controlled research models make it a useful tool for advanced experimental work across a range of laboratory settings.

What is SS-31 studied for?

SS-31 (also known as Elamipretide; previously designated MTP-131) is a synthetic tetrapeptide and a member of the Szeto-Schiller class of mitochondria-associated research peptides developed in academic mitochondrial biology research. As a peptide structure with reported affinity for cardiolipin-rich domains of the inner mitochondrial membrane, SS-31 has been a subject of scientific interest for over two decades. In preclinical and laboratory research, SS-31 has been investigated for its role in mitochondrial bioenergetics, oxidative stress pathway modulation, and cardiolipin interaction studies.

Published studies have explored SS-31 in the context of:

  • Mitochondrial inner membrane and cardiolipin interaction models
  • Reactive oxygen species (ROS) and oxidative stress pathway research
  • Cellular bioenergetics and ATP production studies
  • Ischemia-reperfusion injury models in laboratory and preclinical research
  • Mitochondrial dysfunction models in cardiac, renal, and neuronal cell lines
  • Age-associated mitochondrial decline studies in laboratory models

SS-31 is offered strictly for in vitro research and laboratory use. It is not intended for human or veterinary use, diagnostic application, or therapeutic purposes.

How should SS-31 be stored?

All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months. Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.

Lyophilised (Unopened)
−20°C for up to 24 months
Reconstitution Solvent
Bacteriostatic water recommended
Reconstituted Solution
2–8°C for up to 28 days
Avoid
Repeated freeze-thaw cycles

Handling Notes

Reconstitute slowly by adding solvent to the side of the vial and allowing it to dissolve without agitation. Do not shake. Store away from direct light. All products are shipped with dry ice or cold packs to maintain cold-chain integrity.
