Abstract

Binding proteins, such as antibodies directed to IGF-II with cross-reactivity to IGF-I and uses of such antibodies are described. In particular, fully human monoclonal antibodies directed to the IGF-II with cross-reactivity to IGF-I are disclosed. Also discussed are nucleotide sequences encoding, and amino acid sequences comprising, heavy and light chain immunoglobulin molecules, particularly sequences corresponding to contiguous heavy and light chain sequences spanning the framework regions and/or complementarity determining regions (CDR's), specifically from FR1 through FR4 or CDR1 through CDR3.

First claim

What is claimed is:

1. A nucleic acid molecule encoding an isolated antibody or antibody fragment thereof, wherein said antibody or antibody fragment thereof comprises:
a heavy chain complementarity determining region 1 (hCDR1) having the amino acid sequence set forth in SEQ ID NO: 21 (Ser Tyr Tyr Trp Ser);
a heavy chain complementarity determining region 2 (hCDR2) having the amino acid sequence set forth in SEQ ID NO: 22 (Tyr Phe Phe Tyr Ser Gly Thr Asn Tyr Asn Pro Ser Leu Lys Ser);
a heavy chain complementarity determining region 3 (hCDR3) having the amino acid sequence set forth in SEQ ID NO: 23 (Ile Thr Gly Thr Thr Lys Gly Gly Met Asp Val);
a light chain complementarity determining region 1 (lCDR1) having the amino acid sequence set forth in SEQ ID NO: 30 (Thr Gly Arg Ser Ser Asn Ile Gly Ala Gly Tyr Asp Val His);
a light chain complementarity determining region 2 (lCDR2) having the amino acid sequence set forth in SEQ ID NO: 31 (Gly Asn Ser Asn Arg Pro Ser); and

a light chain complementarity determining region 3 (lCDR3) having the amino acid sequence set forth in SEQ ID NO: 32 (Gin Ser Tyr Asp Ser Ser Leu Ser Gly Ser Val).

2. An isolated host cell comprising the nucleic acid molecule of claim 1 .
