SS-31

Mitochondrial ROS Scavenging

SS-31 localizes to the inner mitochondrial membrane and neutralizes superoxide and hydroxyl radicals, modeling oxidative-stress reduction in cell assays.

Enhanced ATP Production

In isolated mitochondrial preparations, SS-31 preserves electron-transport efficiency and increases ATP yield under stress conditions.

Membrane Stabilization

SS-31 interacts with cardiolipin to maintain cristae structure, supporting studies of mitochondrial integrity in ischemia–reperfusion models.

Anti-Apoptotic Signaling

In neuronal and cardiomyocyte cultures, SS-31 reduces cytochrome-c release and caspase-3 activation, providing a tool for apoptosis-pathway research.

Inflammation & Cytokine Modulation

Preclinical tissue models show SS-31 lowers pro-inflammatory markers (IL-1β, TNF-α), enabling exploration of mitochondrial-linked immune responses.

Lab-Grade Handling & Stability

Reconstitute SS-31 in SWFI or BAC water, store lyophilized at –20 °C, and keep reconstituted solutions at 2–8 °C for up to 7 days with ≥98% peptide integrity.

EXPLORE SS-31

What Is SS-31?

SS-31, also known as Elamipretide, is a cell-permeable tetrapeptide (D-Arg-Dmt-Lys-Phe-NH₂) designed to selectively bind cardiolipin in the inner mitochondrial membrane. In research models, SS-31 is used to probe mitochondrial function, oxidative-stress pathways, and energy-production mechanisms under conditions of metabolic or ischemic challenge.

Why Choose SS-31?

Researchers choose SS-31 for its unparalleled ability to concentrate in mitochondria and neutralize reactive oxygen species at the site of production. Its robust preservation of electron-transport chain efficiency translates into higher ATP levels and reduced apoptotic signaling in diverse cell types. Manufactured under cGMP-like, ISO-certified conditions, every SS-31 batch delivers consistent performance, backed by rigorous HPLC purity testing and endotoxin screening for reliable protocol integration.

What Sets SS-31 Apart?

Unlike general antioxidants, SS-31 uniquely targets the mitochondrial inner membrane by binding cardiolipin, stabilizing cristae structure, and preserving bioenergetic capacity. This dual action—membrane stabilization plus ROS scavenging—allows clear investigation of mitochondrial health, apoptosis, and inflammation without off-target effects. Its demonstrated stability in both lyophilized and reconstituted states ensures reproducible results across in vitro and ex vivo studies.

SS-LUP-332 FAQs

What is SS-31 (Elamipretide) peptide?

SS-31 is a synthetic tetrapeptide (D-Arg-Dmt-Lys-Phe-NH₂) designed to target the inner mitochondrial membrane and scavenge reactive oxygen species in research models.

How does SS-31 protect mitochondria?

By binding cardiolipin, SS-31 stabilizes mitochondrial cristae architecture and neutralizes superoxide and hydroxyl radicals at the source of oxidative stress.

What research applications use SS-31?

SS-31 is used in assays of mitochondrial bioenergetics, oxidative-stress mitigation, apoptosis pathways, and ischemia–reperfusion injury models.

How is SS-31 reconstituted for lab studies?

Reconstitute SS-31 in Sterile Water for Injection (SWFI) or Bacteriostatic Water (BAC) and follow your lab’s SOP for final concentration.

What is the recommended storage for SS-31?

Store lyophilized SS-31 at –20 °C; reconstituted solutions remain stable at 2–8 °C for up to 7 days without significant degradation.

Does SS-31 affect ATP production?

Yes—SS-31 preserves electron-transport efficiency under stress, resulting in higher ATP yield in isolated mitochondrial and cell-based assays.

Can SS-31 be combined with other peptides?

Researchers often co-study SS-31 with antioxidants or anti-inflammatory peptides (e.g., AHK-Cu, BPC-157) to explore synergistic cytoprotection.

Is SS-31 approved for human use?

No. SS-31 is strictly for laboratory research only and is not approved for therapeutic or veterinary application.

What concentrations are typical for SS-31 in cell culture?

In vitro experiments commonly use SS-31 at 0.1–10 µM, depending on cell type and assay endpoints.

Where is SS-31 manufactured and tested?

SS-31 is synthesized in ISO-certified U.S. labs, with each batch validated for ≥99% purity by HPLC and screened for endotoxin (<0.1 EU/mg).
