What are the ammonium gradient liposomes and what they are used for?
Ammonium gradient liposomes are liposomes with ammonium sulfate encapsulated inside. The outside ammonium sulfate has been replaced with a biocompatible solution, such as 10% sucrose or saline. Ammonium liposomes are the best liposome system so far for actively loading weakly basic and lipophilic small molecules.
