By contrast, the CCR5 proteoliposomes that had been formed with 1% rhodamine–DOPE fluoresced intensely and uniformly. No lipid vesicles or other structures >0.1 μm were observed on the surface ...

One such formulation, DC-chol/DOPE liposome, was the first to be tested in human clinical trials in 1992. Like many other similar cationic lipid formulations, DC-chol/DOPE liposome does not ...
