Binding compounds specific for cysteine-rich soluble protein C23
View Patent ↗Nucleic acids encoding a new family of small cysteine rich soluble proteins, 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. An isolated binding compound comprising an isolated antibody or an antigen binding portion thereof that specifically binds to a polypeptide consisting of the amino acid sequence of the C23 polypeptide of SEQ ID NO: 2.
2. A kit comprising:
a) said binding compound of claim 1 ;
b) a compartment for containing said binding compound; and
c) instructions for use of said binding compound.
3. A method of making an antibody of claim 1 , comprising immunizing a mammal with an immunogenic amount of a C23 polypeptide of SEQ ID NO: 2 thereby causing said antibody to be produced.
4. A composition comprising the binding compound of claim 1 and a carrier, wherein said carrier comprises water, saline, and buffer.
5. The binding compound of claim 1 , wherein the antibody specifically binds to a polypeptide consisting of amino acid residues 1-90 of SEQ ID NO: 2.
6. The binding compound of claim 1 , wherein the antigen binding portion is an Fv, Fab, or Fab2 fragment.
7. The binding compound of claim 1 , wherein the binding compound is detectably labeled.
8. The binding compound of claim 7 , wherein the binding compound is detectably labeled with a radioactive or fluorescent label.
9. A method of producing an antigen:antibody complex, comprising contacting a C23 polypeptide with an antibody of claim 1 thereby allowing said complex to form.
10. A composition comprising the binding compound of claim 1 and a carrier, wherein said composition is formulated for oral, rectal, nasal, topical, or parenteral administration.
11. The binding compound of claim 1 wherein the antibody is chimeric or humanized.
