title: [Possibility of the unification of directed drug transport as illustrated by liposome transport to target antigens].
abstract: A new approach to the targeted drug delivery is described. Unlike previous methods, associated with the necessity of specific immunoglobulin immobilization on the surface of drug-containing microcontainer, the present approach permits targeted transport of standardized container to a set of target antigens, using intermediate molecules-mediators possessing high and specific affinity to both vector antibody and standardized container. It was shown that simultaneous targeting of 14C-labeled liposomes to three target antigens using avidin-biotin system permits the increase in liposome binding to target monolayer by 30-50%, as compared to targeting of the same amount of liposomes to one antigen. The method developed is particularly promising in cases when relative availability of target antigens in the target organ is unknown.
