SS-31 – Research Grade Peptide

SS-31 for Laboratory Research

SS-31, also known as Elamipretide or MTP-131, is a synthetic mitochondria-targeting tetrapeptide widely investigated for its interaction with mitochondrial membranes and cellular bioenergetics. Unlike conventional peptides that act through cell-surface receptors, SS-31 has been studied for its affinity for mitochondrial phospholipids, making it an important research tool in mitochondrial biology and cellular metabolism.

Pure Peptides supplies research-grade SS-31 manufactured under rigorous quality standards for qualified laboratory and scientific research.
