DiI-Labeled Fluorescent Control Liposomes for Clophosome® (Neutral)
The fluorescent control liposomes contain the lipophilic dye Dil incorporated in the bilayers. It has comparable physical and chemical attributes as for the Clophosome® except no active is encapsulated inside. It is used for tracking the cellular uptake of the liposomes by common methods like confocal, FACS, etc.
Lipid composition: phosphatidylcholine and cholesterol
Dye: 0.15 mM (0.14mg/mL) (note: the amount of dye has increased from 0.07mg/mL to 0.14mg/mL)
Stability: 6 months for unopened vials
'DiI'; DiIC18(3) (Invitrogen V22889) is a lipophilic membrane dye. It is weakly fluorescent until incorporated into liposome membranes. This orange—red-fluorescent dye, which is spectrally similar to tetramethylrhodamine, is often used as a long-term tracer for neuronal and other cells.
