Antibody fragment-polymer conjugate and humanized anti-IL-8 monoclonal antibody

摘要

(A) A conjugate consisting of one or more antibody fragments covalently attached to one or more non-proteinaceous polymer molecules (NPPMs), where the apparent size of the conjugate is at least 500 kD.Also claimed are: (B) a conjugate formed by one or more antibody fragments covalently attached to one or more NPPMs, where the apparent size of the conjugate is at least 500 kD and where the molecular structure of the conjugate is free of other matter; (C) a conjugate formed by one or more antibody fragments covalently attached to one or more NPPMs, where the apparent size of the conjugate is at least 500 kD, where the antibody fragment incorporates a nonproteinaceous label free of any polymer, and where the molecular structure of the conjugate is free of other matter; (D) a polypeptide selected from a polypeptide that is an anti-IL-8 monoclonal antibody (MAb) or antibody fragment comprising a light chain amino acid sequence comprising the complementarity determining regions (CDRs) of the light chain polypeptide amino acid sequence shown; (E) a nucleic acid molecule that comprises a nucleic acid sequence encoding a polypeptide as in (D); (F) an expression vector comprising a nucleic acid molecule as in (E) operably linked to control sequences recognised by a host cell transfected with the vector; (G) a host cell comprising a vector as in (F).
