Method for blocking binding of CX3C chemokines using CX3C chemokine antibodies
View Patent ↗Nucleic acids encoding a new family of chemokines, the CX3C family, from a mammal, reagents related thereto, including specific antibodies, and purified proteins are described. Methods of using said reagents and related diagnostic kits are also provided.
1. A method for blocking binding of a CX3C chemokine polypeptide to a cell that expresses a receptor for the chemokine; wherein said chemokine polypeptide
a) chemoattracts peripheral blood monocytes or T-cells,
b) consists of an amino acid sequence comprising at least 95% amino acid sequence identity to the amino acid sequence set forth in SEQ ID NO: 8, and
c) comprises a chemokine domain identical to residues 25 to 100 of the amino acid sequence set forth in SEQ ID NO: 8; comprising contacting said chemokine polypeptide with an antibody or antigen-binding fragment thereof that specifically binds to said chemokine polypeptide.
2. The method of claim 1 wherein said antibody or antigen-binding fragment thereof is detectably labeled.
3. The method of claim 1 wherein said antibody or antigen-binding fragment thereof is a polyclonal antibody.
4. The method of claim 1 wherein said antibody or antigen-binding fragment thereof is a monoclonal antibody.
5. The method of claim 1 wherein said antibody or antigen-binding fragment thereof is a Fab.
6. The method of claim 1 wherein said antibody or antigen-binding fragment thereof is a F(ab) 2 .
