Antibodies to claudin-50 polypeptide
View Patent ↗The sequence of a cDNA encoding Claudin-50 and sequence of Claudin-50 protein are disclosed. The cDNA can be used to express the protein or portions thereof or to obtain antibodies capable of specifically binding to the secreted protein. The cDNA may also be used in diagnostic, forensic, gene therapy, and chromosome mapping procedures. The cDNA may also be used to design expression vectors and secretion vectors.

2. The purified or isolated antibody according to claim 1 , further comprising a label.
3. The purified or isolated antibody according to claim 2 , wherein said label is radioactive.
4. The purified or isolated antibody according to claim 2 , wherein said label is fluorescent.
5. The purified or isolated antibody according to claim 2 , wherein said label is an enzymatic label.
6. A kit comprising an antibody according to claim 1 and a reagent allowing the detection of the antigen-antibody complexes formed.
7. The kit according to claim 6 , wherein said antibody is labeled.
8. The kit according to claim 6 , wherein said reagent is labeled.
9. The kit according to claim 6 , wherein said antibody and reagent are labeled.
10. The kit according to claim 6 , further comprising a polypeptide comprising amino acid residues 1–206 of SEQ ID NO: 186.
11. The kit according to claim 6 , further comprising a polypeptide comprising amino acid residues −24 to 206 of SEQ ID NO: 186.
