The present invention provides a compound consisting essentially of the following elements: one or more reactive groups; and two or more cross-linked antibodies or fragments thereof; characterised in that the or each reactive group is suitable for attaching an effector molecule but does not react with any of the antibodies or fragments thereof.
High loading resins (up to 120 nmoles/bead) were preprared by solid-phase dendrimerisation using a novel 1-->3 C-branched isocyanate monomer. (C) 2002 Published by Elsevier Science Ltd.
Solid-phase construction: high efficiency dendrimer synthesis using AB3 isocyanate-type monomers
Solid-phase synthesis is an ideal tool for reactions that require high concentrations and excess reagents and forcing chemical conditions. One such chemistry is that required for dendrimer construction. In this paper the synthesis of a series of symmetrical AB(3) isocyanate-type monomers is reported and used for the preparation of tri-branched dendrimers on the solid-phase. This method not only allows isolable dendrimer but can generate high-loading supports and devices for multivalent presentation. (C) 2003 Elsevier Science Ltd. All rights reserved.
