It possesses the unique capability to freely penetrate cellular and outer mitochondrial membranes independent of mitochondrial membrane potential. In mitochondrial biology, cellular bioenergetics, and aging research, it serves as a primary reference model for studying the structural integrity of the inner mitochondrial membrane (IMM):<\/p>\n<ul>\n<li><strong>Selective Cardiolipin Binding &amp; Cristae Stabilization:<\/strong> Specific electrostatic and hydrophobic interactions with cardiolipin on the inner mitochondrial membrane, preventing pathological cardiolipin peroxidation and stabilizing mitochondrial cristae curvature.<\/li>\n<li><strong>Electron Transport Chain (ETC) Optimization:<\/strong> Facilitates the assembly and structural stability of respiratory supercomplexes (complexes I, III, and IV) and optimizes electron flux via cytochrome c.<\/li>\n<li><strong>Reduction of Mitochondrial ROS Production:<\/strong> Substantially reduces electron leakage and superoxide generation directly at the primary site of origin without quenching physiological redox signaling cascades.<\/li>\n<li><strong>Restoration of ATP Production &amp; mPTP Inhibition:<\/strong> Preserves mitochondrial membrane potential (\u0394\u03a8m), enhances oxidative phosphorylation efficiency, and inhibits the opening of the mitochondrial permeability transition pore (mPTP) in cellular stress and hypoxia\/reperfusion models.<\/li>\n<\/ul>\n<p><strong>Technical &amp; Chemical Specifications<\/strong><\/p>\n<ul>\n<li><strong>Classification:<\/strong> Research Peptide \/ Mitochondria-Targeted Antioxidant &amp; Cristae Stabilizer<\/li>\n<li><strong>Amino Acid Sequence:<\/strong> D-Arg-Dmt-Lys-Phe-NH2 (Dmt = 2&#8242;,6&#8242;-dimethyl-L-tyrosine)<\/li>\n<li><strong>Form:<\/strong> Sterile lyophilized white powder (cake)<\/li>\n<li><strong>Component Identification:<\/strong> Verified via Mass Spectrometry (MS) and analytical HPLC<\/li>\n<li><strong>Recommended Reconstitution Solvent:<\/strong> Sterile bacteriostatic water or sterile phosphate-buffered saline (PBS)<\/li>\n<li><strong>Storage Conditions:<\/strong> Store long-term at -20 \u00b0C in a dry, dark environment.
