Nucleic acids encoding anti-IL-12 antibodies, and methods of production
Isolated nucleic acids encoding an anti-IL-12 antibody 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 nucleic acid molecule encoding an anti-IL-12 antibody, comprising a nucleic acid sequence encoding a heavy chain complementarity determining region 1 (CDR1) amino acid sequence of SEQ ID NO:1, a heavy chain complementarity determining region 2 (CDR2) amino acid sequence of SEQ ID NO:2, a heavy chain complementarity determining region 3 (CDR3) amino acid sequence of SEQ ID NO:3, a light chain complementarity determining region 1 (CDR1) amino acid sequence of SEQ ID NO:4, a light chain complementarity determining region 2 (CDR2) amino acid sequence of SEQ ID NO:5, and a light chain complementarity determining region 3 (CDR3) amino acid sequence of SEQ ID NO:6.
2. A nucleic acid vector comprising the isolated nucleic acid molecule according to claim 1 .
3. An isolated prokaryotic or eukaryotic host cell comprising the isolated nucleic acid molecule according to claim 1 .
4. The isolated host cell according to claim 3 , wherein said host cell is selected from COS-1, COS-7, HEK293, BHK21, CHO, BSC-1, Hep G2, 653, SP2/0, 293, HeLa, myeloma, or lymphoma cells, or any immortalized or transformed cell thereof.
5. A method for producing an anti-IL-12 antibody, comprising translating the nucleic acid molecule according to claim 1 under conditions in vitro, in vivo or in situ, such that the IL-12 antibody is expressed in detectable or recoverable amounts.
6. An isolated nucleic acid molecule encoding an anti-IL-12 antibody that binds to the same region of human IL-12 protein as an antibody comprising heavy chain and light chain CDRs having the amino acid sequences of SEQ ID NOS: 1, 2, 3, 4, 5, and 6.
7. A nucleic acid vector comprising the isolated nucleic acid molecule according to claim 6 .
8. An isolated prokaryotic or eukaryotic host cell comprising the isolated nucleic acid molecule according to claim 6 .
9. An isolated host cell according to claim 8 , wherein said host cell is selected from COS-1, COS7, HEK293, BHK21, CHO, BSC-1, Hep G2, 653, SP2/0, 293, HeLa, myeloma, or lymphoma cells, or any immortalized or transformed cell thereof.
10. A method for producing an anti-IL-12 antibody, comprising translating the nucleic acid molecule according to claim 6 under conditions in vitro, in vivo or in situ, such that the IL-12 antibody is expressed in detectable or recoverable amounts.
