IL-1-like cytokine antibodies
View Patent ↗Nucleic acids encoding mammalian, e.g., primate, IL-1ζ, purified IL-1ζ polypeptides and fragments thereof. Binding proteins, e.g., antibodies, both polyclonal and monoclonal, are also provided. Methods of using the compositions for both diagnostic and therapeutic utilities are provided.
1. An isolated or purified antibody, or antigen binding fragment thereof, that specifically binds to a polypeptide having 95% sequence identity with the amino acid sequence of SEQ ID NO: 2.
2. The isolated or purified antibody, or antigen binding fragment thereof, of claim 1 comprising a monoclonal antibody.
3. The isolated or purified antibody, or antigen binding fragment thereof, of claim 1 comprising a humanized antibody.
4. The isolated or purified antibody, or antigen binding fragment thereof, of claim 1 comprising a human antibody.
5. The isolated or purified antibody, or antigen binding fragment thereof, of claim 1 comprising an Fv, Fab, or F(ab′) 2 fragment of an antibody.
6. The isolated or purified antibody, or antigen binding fragment thereof, of claim 1 further comprising a detectable label.
7. A composition comprising the isolated or purified antibody, or antigen binding fragment thereof, of claim 1 and a carrier, wherein the carrier comprises water, saline or buffer.
8. A composition comprising the isolated or purified antibody, or antigen binding fragment thereof, of claim 1 and a carrier, wherein the composition is formulated for oral, rectal, nasal, topical, or parenteral administration.
9. A method of making the isolated or purified antibody, or antigen binding fragment thereof, of claim 1 , comprising:
a) immunizing an animal with an immunogenic amount of the polypeptide of SEQ ID NO: 2; and
b) isolating an antibody that binds to the polypeptide of SEQ ID NO: 2 from said animal after immunization.
10. A method of producing an antigen:antibody complex, comprising:
a) contacting a polypeptide comprising the amino acid sequence of SEQ ID NO: 2 with the antibody of claim 1 ; and
b) allowing the complex to form.
11. An isolated or purified antibody, or antigen binding fragment thereof, raised against a polypeptide having 95% sequence identity with the amino acid sequence of SEQ ID NO: 2.
12. The isolated or purified antibody, or antigen binding fragment thereof, of claim 11 comprising a monoclonal antibody.
13. The isolated or purified antibody, or antigen binding fragment thereof, of claim 11 comprising a humanized antibody.
14. The isolated or purified antibody, or antigen binding fragment thereof, of claim 11 comprising a human antibody.
15. The isolated or purified antibody, or antigen binding fragment thereof, of claim 11 comprising an Fv, Fab, or F(ab′) 2 fragment of an antibody.
16. The isolated or purified antibody, or antigen binding fragment thereof, of claim 11 further comprising a detectable label.
17. A composition comprising the isolated or purified antibody, or antigen binding fragment thereof, of claim 11 and a carrier, wherein the carrier comprises water, saline or buffer.
18. A composition comprising the isolated or purified antibody, or antigen binding fragment thereof, of claim 11 and a carrier, wherein the composition is formulated for oral, rectal, nasal, topical, or parenteral administration.
19. A method of making the isolated or purified antibody, or antigen binding fragment thereof, of claim 11 , comprising:
a) immunizing an animal with an immunogenic amount of the polypeptide of SEQ
ID NO: 2; and
b) isolating an antibody that binds to the polypeptide of SEQ ID NO: 2 from said animal after immunization.
20. A method of producing an antigen:antibody complex, comprising:
a) contacting a polypeptide comprising the amino acid sequence of SEQ ID NO: 2 with the antibody of claim 11 ; and
b) allowing the complex to form.
