EP9
Based on 1 Customer Validation
EP9 is a peptide targeting CD63. EP9 binds specifically to the extracellular region of CD63, including a groove in the large extracellular loop (EC2) or the extracellular end of CD63’s central cavity, triggering endocytosis of decorated nanoemulsions/liposomes into cells. EP9 promotes cellular uptake of decorated nanoemulsions/liposomes into activated cardiac fibroblasts and epicardial stromal cells via caveolae and/or clathrin-coated pits. EP9 can be used for the research of myocardial infarction, cardiac fibrosis.

Biological Activity
EP9 (5 µg; 30 min) binds specifically to mouse cardiac fibroblasts and EpiSC, human primary cardiac fibroblasts, and normal human dermal fibroblasts, with the highest binding affinity for mouse EpiSC and human primary cardiac fibroblasts[1].
EP9 (1 mM; 1 h) specifically binds to the tetraspanin CD63, a transmembrane protein on the surface of normal human dermal fibroblasts, as confirmed by significant enrichment in EP9 probe samples relative to control MUT probe samples[1].

Animal Model:C57BL/6J (male, 8-12 weeks old, 20-25 g, myocardial infarction induced by 50 min left anterior descending coronary artery ligation followed by reperfusion)[1]
-
Dosage:25 µg EP9 per 100 µL PFC-NE; 150 µL EP9-PFC-NE
-
Administration:i.v.; single dose
-
Result:Localized a strong 19F signal specifically to the infarcted anterior wall of the left ventricle on in vivo MRI, with a signal-to-noise ratio significantly higher than that of the mutated peptide control.
Declined plasma 19F signal with a half-life of ~20 hours.
Showed a transmural 19F signal in the infarcted area that increased between 12 hours and 24 hours post-injection via ex vivo MRI.
Revealed EP9-PFC-NE uptake primarily by cardiac fibroblasts and epicardial stromal cells, with no detectable uptake in macrophages, cardiomyocytes, or endothelial cells via transmission electron microscopy.
Demonstrated intracellular particles had an average size of 118 nm, matching the pre-injection particle size of 124 nm.
