Lipids for Active Targeting
Surface modification on liposomes is a very effective method to control their physical and biological behaviours.
Specific receptor antigens such as antibodies, peptides or sugar moieties can make liposomes preferentially target certain tissues or cell types.
Such Immunoliposomes are used in both, therapeutic and diagnostic applications.
For use with Long Circulating Liposomes (PEGylated) antigen modified PEG-Lipids are needed in order to prevent shielding of the receptor antigen.
