SS-31 research overview
SS-31, also known by the name elamipretide, is a synthetic tetrapeptide from the Szeto-Schiller family that concentrates in the inner mitochondrial membrane, where it associates with the phospholipid cardiolipin. TrueBond Labs offers SS-31 as a 50 mg lyophilized vial produced for laboratory work. Independent HPLC analysis verifies a minimum of 99% purity and mass-spectrometry testing confirms molecular identity before any lot is released, so researchers who buy SS-31 here receive fully documented material.
SS-31 has been studied in preclinical research examining mitochondrial bioenergetics, membrane-lipid interactions, and cellular models of oxidative stress. Its affinity for cardiolipin has made it a frequently cited tool compound in laboratory investigations of electron-transport-chain function and mitochondrial membrane organization. Such publications map out fields of study rather than established effects, and this research peptide is supplied solely for in-vitro experimentation by qualified professionals — never for human or animal use.
At 50 mg per vial, this format suits research programs that require larger peptide quantities across an experiment series. The lot-specific certificate of analysis covering HPLC purity and MS identity is available at /lab-reports. Lyophilized SS-31 holds stability at −20°C for 24+ months; reconstituted material belongs at 2–8°C and should be used within about 30 days. The current batch, TB-S31-001, documented 99.4% purity across its 50.3 mg net fill.

SS-31 — frequently asked questions
What is SS-31 (elamipretide)?+
SS-31, or elamipretide, is a four-amino-acid synthetic peptide of the Szeto-Schiller class that localizes to the inner mitochondrial membrane through its interaction with cardiolipin. It appears in preclinical laboratory studies of mitochondrial bioenergetics and oxidative-stress models. TrueBond Labs provides it strictly as a research compound for in-vitro use by qualified professionals.
Is SS-31 purity independently verified?+
It is. Every SS-31 batch undergoes independent third-party testing before release: HPLC quantifies purity, which must reach at least 99%, and mass spectrometry establishes identity. The complete lot-level certificate of analysis is published at /lab-reports, and each vial's lot marking corresponds to that document.
How long does lyophilized SS-31 remain stable?+
In its lyophilized state, SS-31 stays stable for 24 or more months when kept at −20°C and protected from light. Following reconstitution for bench research, refrigerate the solution at 2–8°C and plan experiments around a working window of roughly 30 days. Minimize freeze/thaw cycling to preserve integrity.
