Abstract: A reagent for conjugation to a biomolecule, wherein the reagent is a single molecule with at least three functional parts and has schematic structure (I): a) wherein a trifunctional cross-linking moiety is coupled to b) an affinity ligand via a linker 1, said affinity ligand being capable of binding with another molecule having affinity for said ligand, to c) an effector agent, optionally via a linker 2, said effector agent exerting its effect on cells, tissues and/or humorous molecules in vivo or ex vivo, and to d) a biomolecule reactive moiety, optionally via a linker 3, said moiety being capable of forming a bond between the reagent and the biomolecule.

Abstract: A conjugate comprising a) a trifunctional cross-linking moiety, to which is coupled b) an affinity ligand via a linker 1, c) a cytotoxic agent, optionally via a linker 2, and d) an anti Erb antibody or variants thereof having the ability to bind to Erb antigens expressed on mammalian tumour surfaces with an affinity-binding constant of at least 5×106 M?1, wherein the affinity ligand is biotin, or a biotin derivative having essentially the same binding function to avidin or streptavidin as biotin, wherein stability towards enzymatic cleavage of the biotinamide bond has been introduced in linker 1.

Abstract: The present invention provide methods to improve the treatment of cancer in mammals, including ovarian cancer, where intraperitoneal administration of cytotoxic medical agents or immunoconjugates are utilized. The invention provides means of substantially reducing the level of cytotoxic medical agents or immunoconjugates in the circulating blood. Hence, the organ exposure of circulating cytotoxic agents is minimized using the invention and the invention offers opportunities to use more effective dose treatment regime.

Abstract: An apparatus for use in connection with removal of elements, especially exogenous antibodies, from blood or plasma flowing in an extracorporeal blood circulation system of a patient, where said apparatus comprises a container (1). This container is adapted to receive an adsorbent and comprises an inlet (15) and an outlet (16) which are adapted to be connected to an inlet conduit (19) and an outlet conduit (20), respectively, forming part of the blood circulation system. The container (1) comprises an inlet chamber (31), an adsorption chamber (32) adapted to receive the adsorbent, and an outlet chamber (33). These chambers are arranged in sequence when seen in the flow direction of the blood or the plasma through the container (1) and are separated by means of filter units (11, 12) allowing passage of the blood or the plasma. The inlet (15) and the outlet (16) are arranged adjacent one another in connection with a common movable valve means (21).

Abstract: A method for the conditioning of an extracorporeal device is described, as well as a method for extracorporeal extraction of toxic material from mammalian body fluids in connection with diagnosis or treatment of a mammalian condition or disease, in which methods reagents having the ability to extract toxic material from mammalian body fluids are involved, and an extracorporeal device comprising said reagent.
