Abstract

Branched molecular scaffolds are provided which are capable of linking two polymer residues (derived, for example, from polyethylene glycol) to two, three or four residues derived from biologically active molecules (e.g. from whole antibodies or from functionally active fragments or derivatives thereof), the latter being attached to the scaffold by means of hydrolytically stable linkages.
