    摘要: Bis-maleimido cross-linking reagents join labelled antibodies having at least one sulphide interchain bridge. The conjugates have an enhanced binding capacity and have good blood clearance in vivo. The conjugates are of use in the diagnosis and therapy of tumors and may be prepared by reaction of the cross-linking reagent with the antibody.

    摘要: Cross-linked labelled antibody conjugates are described which have at least one non-disulphide interchain bridge. The bridge may be the residue of a homo- or heterofunctional cross-linking reagent, and is located away from the antigen binding domains of the antibody. The antibody conjugates have an enhanced binding capacity and in vivo have good blood clearance and, in the presence of a tumour high tumour: blood and tumour: bone ratios. The conjugates are of use in the diagnosis and therapy of e.g. tumours and may be prepared by reaction of a cross-linking reagent with an antibody.
