About SS-31 as a reference compound
SS-31 is a cardiolipin-binding tetrapeptide reference compound used in mitochondrial-function assays. Every PureLabs lot is produced under GMP-aligned synthesis controls, filled and sealed in a controlled environment, then assayed by an independent partner laboratory using reverse-phase HPLC with mass-spectrometric confirmation. Material is released only at or above the stated 98.8% threshold; anything below it is rejected rather than sold. The certificate of analysis carries the chromatogram and MS trace for the exact lot you receive and stays archived under reference PL-1147 for the life of the batch. Available in 2 kit configurations, each containing ten vials.
Handling and storage
- Store sealed SS-31 vials at −20 °C, protected from light.
- Reconstitute with bacteriostatic or sterile water added slowly down the vial wall; swirl, never shake.
- Hold reconstituted solution at 2–8 °C and use within roughly 21 days.
- Aliquot before freezing so the material never sees repeated freeze–thaw cycles.
SS-31 — frequently asked questions
Common laboratory questions about sourcing, purity, storage and shipping of SS-31.
What sizes of SS-31 can I order?
SS-31 ships in 2 configurations: 10 mg/vial · 10 vials/kit; 50 mg/vial · 10 vials/kit. Prices start at $115 per kit.
What purity is PureLabs SS-31?
Current stock assays at 98.8% by reverse-phase HPLC with mass-spectrometric confirmation from an independent laboratory. Lots below the threshold never reach the catalog.
Does SS-31 ship with a certificate of analysis?
Yes. A lot-specific certificate of analysis including the HPLC chromatogram and MS trace accompanies every order and remains retrievable under batch reference PL-1147.
How should SS-31 be stored?
Sealed lyophilized SS-31 is stable at −20 °C for at least 24 months. Once reconstituted, hold at 2–8 °C and use within about three weeks.
How quickly does SS-31 ship?
Orders confirmed before 15:00 UTC dispatch the same working day in insulated, tracked packaging, subject to the import rules of the destination country.
Is SS-31 sold for human use?
No. PureLabs supplies this material strictly as a reference compound for in-vitro and laboratory research. It is not a medicine and is not for human or veterinary consumption.
