Surface modified liposomes |
abstract |
SURFACE MODIFIED LIPOSOMES ABSTRACT OF THE DISCLOSURE A liposome reagent encapsulating a molecule to be targeted to a body site or used as an assay reporter has a ligand and a sulfonate-containing group on the liposome surface. Preferred ligands are antibodies or antibody fragments and preferred encapsulants are enzymes or dyes. In the most preferred reagents, the antibody and sulfonate-containing group are covalently bonded to the liposome surface through a connecting group which includes a succinimidyl group resulting from addition of the ligand or sulfonate-containing group to a maleimidyl group. The invention includes a kit of materials for performing an assay using the reagent of the invention as the tracer. |
