Anti-IL-12 antibodies and compositions
Isolated anti-IL-12 antibodies, nucleic acids encoding antibodies or antibody portions, vectors, host cells, and methods of making are useful for production of antibody or portions for treating and/or diagnosing IL-12 related conditions, diseases, and disorders.
1. An isolated anti-IL-12 antibody, comprising a heavy chain complementarity determining region 1 (CDR1) comprising an amino acid sequence with not more than one conservative substitution from the amino acid sequence of SEQ ID NO:1, a heavy chain complementarity determining region 2 (CDR2) comprising an amino acid sequence with not more than one conservative substitution from the amino acid sequence of SEQ ID NO:2, a heavy chain complementarity determining region 3 (CDR3) comprising an amino acid sequence with not more than one conservative substitution from the amino acid sequence of SEQ ID NO:3, a light chain complementarity determining region 1 (CDR1) comprising an amino acid sequence with not more than one conservative substitution from the amino acid sequence of SEQ ID NO:4, a light chain complementarity determining region 2 (CDR2) comprising an amino acid sequence with not more than one conservative substitution from the amino acid sequence of SEQ ID NO:5, and a light chain complementarity determining region 3 (CDR3) comprising an amino acid sequence with not more than one conservative substitution from the amino acid sequence of SEQ ID NO:6, wherein the antibody is a variant of the antibody comprising an heavy chain CDR1 amino acid sequence of SEQ ID NO:1, the heavy chain CDR2 amino acid sequence of SEQ ID NO:2, the heavy chain CDR3 amino acid sequence of SEQ ID NO:3, the light chain CDR1 amino acid sequence of SEQ ID NO:4, the light chain CDR2 amino acid sequence of SEQ ID NO:5, and the light chain CDR3 amino acid sequence of SEQ ID NO:6.
