生物活性

製品説明	Elamipretide (MTP-131, SS-31) is a cytochrome c peroxidase inhibitor. Elamipretide improves mitochondrial dysfunction, synaptic and memory impairment induced by lipopolysaccharide in mice.
in vitro	Elamipretide (SS-31, MTP-131) binds with high affinity to cardiolipin, an anionic phospholipid expressed on the inner mitochondrial membrane that is required for cristae formation. In addition, the complex formed with cardiolipin inhibits cytochrome c peroxidase activity, which catalyzes cardiolipin peroxidation and results in mitochondrial damage during ischemia, by protecting its heme iron.^[1]
in vivo	Pretreatment of rats with Elamipretide (SS-31, MTP-131) protects cristae membranes during renal ischemia and prevents mitochondrial swelling. Prompt recovery of ATP on reperfusion leads to rapid repair of ATP-dependent processes, such as restoration of the actin cytoskeleton and cell polarity. Rapid recovery of ATP also inhibits apoptosis, protects tubular barrier function, and mitigates renal dysfunction.^[1]

細胞アッセイ	細胞株	feline kidney cells
	濃度	0.1-10 μM
	反応時間	1 hour
	実験の流れ	Intracellular targeting of Elamipretide (SS-31, MTP-131) is determined by incubating feline kidney cells, grown in biotin-free media for 24 hours, with biotinylated SS-31 for 1 hour. Cells are then fixed with 4% paraformaldehyde, permeabilized with 0.1% triton, and treated with Streptavidin-AlexaFluor594 for 30 minutes at room temperature. Fluorescence staining is observed by wide-field fluorescent microscope.
