Mammalian cell surface antigens; related reagents
View Patent ↗Purified genes encoding a T cell surface antigen from a mammal, reagents related thereto including purified proteins, specific antibodies, and nucleic acids encoding this antigen are provided. Methods of using said reagents and diagnostic kits are also provided.
1. An antibody or antigen binding fragment thereof which specifically binds a protein or peptide of at least 8 amino acids of SEQ ID NO:2 or 4,
wherein said antibody or antigen binding fragment thereof is specifically immunoreactive with the protein of SEQ ID NO:2 or 4 and not with other proteins.
2. A sterile or buffered composition comprising the antibody of claim 1 .
3. A labeled antibody or antigen binding fragment thereof, wherein the antibody or antigen binding fragment thereof of claim 1 is detectably labeled.
4. An antibody or antigen binding fragment thereof attached to a solid substrate, wherein said antibody or antigen binding fragment thereof of claim 1 is attached to said solid substrate.
5. The antibody or antigen binding fragment thereof of claim 1 , wherein the antibody is a:
a) polyclonal antibody; or
b) monoclonal antibody.
6. The antibody or antigen binding fragment thereof of claim 1 , wherein the antigen binding fragment is a:
a) Fab fragment;
b) Fab′ fragment; or
c) F(ab) 2 fragment;
d) Fv fragment.
7. The antibody or antigen binding fragment thereof of claim 1 , wherein said antibody is a humanized antibody or an antigen binding fragment thereof.
8. A kit comprising
a) a detectably labeled antibody or antigen binding fragment thereof which specifically binds a protein or peptide of at least 8 amino acids of SEQ ID NO:2 or 4,
wherein said antibody or antigen binding fragment thereof is specifically immunoreactive with the protein of SEQ ID NO:2 or 4 and not with other proteins;
b) a protein or peptide of at least 8 amino acids of SEQ ID NO:2 or 4 immobilized to a solid support; and
c) instructions for use.
