SKU: UB-31

UB-31

UB-31 is a synthetic, water-soluble tetrapeptide from the Szeto-Schiller peptide family. It is characterized by an alternating aromatic and cationic amino acid motif and a C-terminal amide.

In published in vitro literature, UB-31 has been described as localizing to the inner mitochondrial membrane and binding the phospholipid cardiolipin. This material is supplied as a characterized reference compound for non-clinical laboratory work, such as analytical method development, peptide-lipid binding assays, and isolated mitochondria or cell culture studies of membrane biochemistry.
