SS-31 10mg

Sign in for priceIn stock

SS-31 (elamipretide) is a cell-permeable tetrapeptide, D-Arg-Dmt-Lys-Phe-NH2, that concentrates in the inner mitochondrial membrane through association with cardiolipin. It is studied for effects on cristae structure and electron transport efficiency.

About SS-31 10mg

SS-31 targets cardiolipin, the signature phospholipid of the inner mitochondrial membrane, and its alternating aromatic-cationic motif is what drives that association without requiring a membrane potential to accumulate. Binding cardiolipin stabilises cristae architecture and appears to improve electron transport coupling, which is the mechanistic basis for interest in ischemia-reperfusion, heart failure and mitochondrial myopathy models. The compound has run through several clinical programmes under the name elamipretide, so its pharmacokinetics are better characterised than most research peptides.

Storage and reconstitution

Store lyophilized peptide at -20°C in a dry, dark environment. Reconstitute in bacteriostatic water. Once reconstituted, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles. Lyophilized powder is stable at room temperature for shipping and short-term storage.

Shipping within Canada

Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Parcels leave British Columbia, Canada and travel entirely within the country, so nothing on this order crosses a border, clears customs or is held by CBSA. Orders over CA$200 ship free; see the shipping page for transit times by province.
