Patent ID: 7772372

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 26-34, 52-58 and 97-103 of SEQ ID NO:5, or wherein the heavy chain (V H ) variable region sequence comprises amino acids 11-18, 36-43, and 82-100 of SEQ ID NO:7, and wherein said antibody or said antigen binding fragment specifically binds to an epitope of a polypeptide having an approximate molecular weight of 115 kDa using sodium dodecyl sulfate polyacrylamide gel electrophoresis, wherein said polypeptide is expressed by ASPC-1(ATCC Accession No. CRL-1682) or BXPC-3 (ATCC Accession No. CRL-1687) cells and wherein PM-2 antibody produced by a cell line deposited as DSM ACC2600 specifically binds to said epitope of the polypeptide having an approximate molecular weight of 115 kD expressed by ASPC-1 (ATCC Accession No. CRL-1682) or BXPC-3 (ATCC Accession No. CRL-1687) cell.
