Abstract: An antibody, or an antigen-binding fragment thereof, that binds specifically to human CSF-1R includes a heavy chain variable domain that contains a HCDR1 region having the sequence of SEQ ID NO: 4, a HCDR2 region having the sequence of SEQ ID NO: 5, and a HCDR3 region having the sequence of SEQ ID NO: 6; and a light chain variable domain that contains a LCDR1 region having the sequence of SEQ ID NO: 7, a LCDR2 region having the sequence of SEQ ID NO: 8, and a LCDR3 region having the sequence of SEQ ID NO: 9. The heavy chain variable domain comprises the sequence of SEQ ID NO: 2, and wherein the light chain variable domain comprises the sequence of SEQ ID NO: 3.
