Fluorescent DOPC/CHOL Liposomes labeled with Fluorescein DHPE (200nm)

Fluorescent DOPC/CHOL Liposomes labeled with Fluorescein DHPE (200nm)High quality LUV liposomes labeled with fluorescein DHPE are ready to use. The liposomes are prepared by the extrusion technology to 200-250nm nm with tight particle size distribution. The product is semisterile filtered through 0.45um filters and filled in autoclaved vials guaranteed to be stable for 3 months stored in refrigerator. The phospholipid, fluorescein DHPE is labeled on the head group with the green-fluorescent pH-sensitive fluorophore, fluorescein (excitation/emission maxima ~496/519 nm). Lipid composition: DOPC/CHOL/Fluorescein-DHPE (54:45:1 mol/mol)Lipid concentration: 50 mM (50-55 mM)Fluorscein DHPE: 0.5 mM (0.59 mg/mL)Mean particle size: 230 nm (200-250 nm, intensity weighted lognormal per DSL)Particle size distribution: 80-100nm (half-width)Hydration buffer: 10% sucrose, 20mM HEPES, pH 7.5 ± 0.2Storage: in refrigerator (2 - 8 degree C)Shelf-life: 3 month for unopened vials, protect from light
