Single domain antibodies that bind to human CD20
Described herein is the development of recombinant single domain antibodies, also known as nanobodies, that may provide better therapeutic results or be useful for diagnostic applications of B-cell lymphomas, or in other applications where an antibody to CD20 may be useful.
1. An isolated anti-CD20 single domain antibody comprising the amino acid sequence of SEQ ID NO: 2, SEQ ID NO: 5, or SEQ ID NO: 6.
2. The isolated anti-CD20 single domain antibody of claim 1 , wherein the amino acid sequence is that of SEQ ID NO: 2 or SEQ ID NO: 6.
3. An isolated anti-CD20 single domain antibody comprising the amino acid sequence of SEQ ID NO: 16.
4. A pharmaceutical composition comprising:
an isolated anti-CD20 single domain antibody comprising the amino acid sequence of SEQ ID NO: 2, SEQ ID NO: 5, or SEQ ID NO: 6;
and a pharmaceutically acceptable carrier.
5. The pharmaceutical composition of claim 4 , wherein the amino acid sequence is that of SEQ ID NO: 2 or SEQ ID NO: 6.
6. A pharmaceutical composition comprising:
an isolated anti-CD20 single domain antibody comprising the amino acid sequence of SEQ ID NO: 16;
and a pharmaceutically acceptable carrier.
