Anti-Notch3 antibodies
The present invention relates to novel antibodies that bind specifically to human Notch 3 and their use in the detection and/or diagnosis of Notch 3 related diseases, such as cancer. The present invention also includes nucleic acids encoding these novel antibodies, vectors and cell lines harboring the nucleic acids, and kits comprising the antibodies for use in the detection and diagnosis.
1. An isolated antibody comprising a variable light (VL) chain region comprising the amino acid sequence of SEQ ID NO: 5, wherein the antibody binds specifically to Notch3.
2. An isolated antibody comprising a variable heavy (VH) chain region comprising the amino acid sequence of SEQ ID NO: 4, wherein the antibody binds specifically to Notch3.
3. The antibody of claim 1 , further comprising a variable heavy (VH) chain region comprising the amino acid sequence of SEQ ID NO: 4.
4. An isolated antibody comprising a variable heavy (VH) chain region comprising complementarity determining regions (CDRs) of SEQ ID NO: 14, 15, and 16, wherein the antibody binds specifically to Notch3.
5. An isolated antibody comprising a variable light (VL) chain region comprising complementarity determining regions (CDRs) of SEQ ID NO: 17, 18, and 19, wherein the antibody binds specifically to Notch3.
6. The antibody of claim 4 , further comprising a variable light (VL) chain region comprising CDRs of SEQ ID NO: 17, 18, and 19.
7. The antibody of any of claims 1 - 3 , 4 - 5 , and 6 , wherein the antibody is an antibody fragment.
8. The antibody of claim 7 , wherein the antibody is a single chain Fv.
9. The antibody of any of claims 1 - 3 , 4 - 5 , and 6 , further comprising a label.
