Patent ID: 7816496

Claim:
A biologically active recombinant antibody or biologically active recombinant antibody fragment which specifically binds to an MN protein or to an MN polypeptide, wherein said MN protein or MN polypeptide is encoded by a nucleic acid selected from the group consisting of: (a) SEQ ID NO: 1; (b) nucleotide sequences that hybridize under stringent hybridization conditions of 50% formamide at 42° C. to complement of SEQ ID NO: 1's coding region; and (c) nucleotide sequences that differ from SEQ ID NO: 1 or from the nucleotide sequences of (b) due to the degeneracy of the genetic code; and wherein said recombinant antibody or recombinant antibody fragment specifically binds to the MN protein having the amino acid sequence of SEQ ID NO: 2.
