Patent ID: 7435554

Claim:
A method of detecting the presence and extent of small cell lung cancer (SCLC) in a patient in need thereof comprising: a) contacting a sample from said patient with a monoclonal antibody or fragment thereof under conditions that allow said monoclonal antibody or fragment thereof to specifically bind an antigen associated with SCLC wherein said monoclonal antibody is i) a monoclonal antibody produced from the hybridoma cell line deposited at the American Type Culture Collection (ATCC) having ATCC Accession No. PTA-2360 (MoAb 51.2), PTA-2357 (MoAb 109.12), PTA-2358 (MoAb 37.14), or PTA-2359 (MoAb 26.1) or ii) a monoclonal antibody which specifically recognizes an epitope of an antigen present on the surface of SCLC cells, said antigen is recognizable by a monoclonal antibody produced from the hybridoma cell line deposited at the American Type Culture Collection (ATCC) having ATCC Accession No. PTA-2360 (MoAb 51.2), PTA-2357 (MoAb 109.12), PTA-2358 (MoAb 37.14), or PTA-2359 (MoAb 26.1); and b) determining the level of binding of said monoclonal antibody or fragment thereof to said antigen; wherein there is a correlation between the amount of binding of said monoclonal antibody or fragment thereof with the presence and extent of SCLC in said patient.
