SS-31 50mg

SS-31 50mg is a 50mg vial of SS-31, a mitochondria-targeted tetrapeptide, supplied as freeze-dried powder. It’s for in-vitro and lab research only.

SS-31 at a glance

SS-31, also called elamipretide, is a four-amino-acid peptide: D-Arg-Dmt-Lys-Phe-NH2. It alternates positive charges with aromatic rings, a design that lets it slip through cell membranes and collect in mitochondria.

Once there, it binds cardiolipin, a fat that’s found almost only in the inner mitochondrial membrane and that holds the energy-making machinery in place.

How SS-31 works

Cardiolipin holds together the protein complexes that make ATP in mitochondria. When it’s oxidized, those complexes work less well and leak more free radicals.

SS-31 binds cardiolipin and protects it, which in lab studies kept the electron transport chain working more efficiently and cut oxidative damage. It doesn’t depend on the membrane voltage to get into mitochondria, which sets it apart from other targeted antioxidants.

What the research says about SS-31

Hazel Szeto and Peter Schiller designed it in the early 2000s; SS stands for Szeto-Schiller. Stealth BioTherapeutics took it into clinical trials for mitochondrial diseases, including primary mitochondrial myopathy and Barth syndrome.

It’s one of the few mitochondria-targeted peptides with real human trial data. This vial is research material, not the clinical product.

How to reconstitute SS-31 50mg

Here’s the math for 50mg of powder:

• 2mL of bacteriostatic water gives 25mg/mL
• 3mL of bacteriostatic water gives 16.67mg/mL
• 5mL of bacteriostatic water gives 10mg/mL

Pick the volume that keeps your own calculations simple, then write the concentration and the mixing date on the label.

Bacteriostatic water is the usual choice, and acetic acid helps with peptides that won’t dissolve in water alone. Add it slowly so it runs down the side of the vial, then swirl or roll until everything dissolves. Shaking can shear peptide chains. Skip it.

How to store SS-31 50mg

Store sealed vials of SS-31 50mg in the freezer at -20°C, out of direct light. Mixed solution goes in the fridge at 2 to 8°C and should be used within about 28 days.

Running several vials at once? Our 10 vial kit case holds up to ten vials upright in separate wells under a clear lid, which keeps a fridge shelf tidy and the labels easy to read.

SS-31 50mg quality notes

The vial label shows the compound and the amount. For anything your lab needs on file beyond that, email Peptira support with the product name before you place the order.

Labs that check material in-house normally confirm identity with mass spectrometry, which checks the molecular weight, and measure purity with HPLC, which separates the main compound from anything else in the sample.

Write the order date and the vial details into your lab notes. If a result looks odd later, you can tie it back to the exact material you used.

Other SS-31 strengths

• SS-31 10mg: $49.00, about $4.90 per mg
• SS-31 50mg (this page): $139.00, about $2.78 per mg

SS-31 50mg is one of the larger sizes, and bigger vials usually cost less per milligram. It suits longer studies where you’d otherwise reorder.

Planning a study with SS-31 50mg

Work out the total amount before you order. Add up what each arm of the study uses across every time point, then divide by 50mg. Round up by one vial so a spoiled sample or a repeat run doesn’t stall the project.

Mix one vial at a time and keep the rest sealed in the freezer. Dry powder keeps far longer than solution, so there’s no reason to reconstitute everything at the start.

Keep vials from one batch together in a study where you can. The batch number on the label ties each result back to the lab paperwork.
