Patent ID: 7741444

Claim:
A purified antibody or antigen binding fragment thereof comprising a light chain (V L ) variable region sequence and a heavy chain (V H ) variable region sequence, wherein the light chain (V L ) variable region sequence comprises amino acids 26-31, 49-51, and 88-95 of SEQ ID NO:1, or wherein the heavy chain (V H ) variable region sequence comprises amino acids 11-18, 36-43, and 82-90 of SEQ ID NO:3, and wherein said antibody or antigen binding fragment specifically binds to an epitope of a polypeptide expressed by at least one of ASPC-1 (ATCC Accession No. CRL-1682), or BXPC-3 (ATCC Accession No. CRL-1687) cells, and wherein PM-1 antibody produced by a cell line deposited as DSM ACC 2599 specifically binds to said epitope of the polypeptide expressed by at least one of ASPC-1(ATCC Accession No. CRL-1682), or BXPC-3 (ATCC Accession No. CRL-1687) cells.
