Abstract

The invention generally provides improved anti-sickled-globin antibodies and fragments thereof. In particular embodiments, the antibody or antigen binding fragment thereof recognizes the βs, Glu6Val mutation. In various embodiments, the invention provides a conjugate comprising an anti-βs-globin antibody or antigen binding fragment thereof and a detectable label. In particular embodiments, a hybridoma comprising an anti-βs-globin antibody contemplated herein is provided.

Claims (5)

1. An anti-β S globin antibody or antigen binding fragment thereof that binds a human βS globin polypeptide, wherein the anti-β S globin antibody or antigen binding fragment thereof comprises a variable light chain sequence as set forth in SEQ ID NO: 7 and a variable heavy chain sequence as set forth in SEQ ID NO: 8.

2. A conjugate, comprising the anti-β S globin antibody or antigen binding fragment thereof of claim 1 ; and a detectable label.

3. The conjugate of claim 2 , wherein the detectable label is selected from the group consisting of: a hapten, a fluorescent dye, a fluorescent protein, a chromophore, a metal ion, a gold particle, a silver particle, a magnetic particle, a polypeptide, an enzyme, a luminescent compound, or an oligonucleotide.

4. A hybridoma comprising the anti-β S globin antibody of claim 1 .

5. A polynucleotide encoding the anti-β S globin antibody or antigen binding fragment thereof of claim 1 .
