Abstract: The present invention is concerned with a novel antigens associated with human tumors, including carcinomas of the colon or lung, as well as novel monoclonal antibodies which specifically bind to said antigen. The antibodies bind to normal human cells to a much lesser degree than to tumor cells. The antigens include 100 kDa glycoprotein that has a colorectal cancer membrane bound and a soluble form, has a UV absorbance peak at about 228 nm, an isoelectric point of about 3.5 to 4, a sialic acid content of about 20%, and does not substantially bind to an antibody specific for ACT. The antibodies find use both in methods such as the detection of malignant cells associated with tumors and in monitoring therapeutic treatment of humans with tumors.

Abstract: The present invention is concerned with a novel antigen associated with human tumors, including carcinomas of the colon, pancreas, and lung, as well as novel monoclonal antibodies which binds strongly to said antigen. The antibodies bind to normal human cells to a much lesser degree than to tumor cells. The antibodies find use both in diagnostic methods such as the detection of malignant cells associated with tumors and in therapeutic methods for treatment of humans with tumors. The novel antigen disclosed is a 60,000 Dalton glycoprotein found on the cell surface of human tumor cells.
Abstract: The present invention provides antibodies which specifically bind early conception factor, which can be found in body fluids of animals including but not limited to the cow, cat, dog, horse, human, sheep, and pig. The invention provides methods for detecting conception or the absence of conception in an animal, the latter being recognized by the absence of early conception factor in a suitable body fluid collected from the animal. Apparati for detecting early conception factor in a body fluid from an animal comprising the antibodies which specifically bind early conception factor are also provided.
