    • A substantially purified cancer-related galactosyltransferase and a monoclonal antibody which may be used as a diagnostic reagent of cancer are disclosed. The galactosyltransferase of the present invention has a molecular weight of about 50,000 determined by SDS-polyacrylamide gel electrophoresis under reducing conditions and has a reactivity with MAb4880 under native conditions. A part of the galactosyltransferase self-associates and its reactivity with MAb4880 and the degree of self-association are promoted when it is reduced so that a part of which is detected in a fraction of a molecular weight of not less than 200,000 in gel permeation chromatography. The galactosyltransferase of the present invention can be used as a cancer marker or as a reagent for preparing a monoclonal antibody with a specificity to the galactosyltransferase, which monoclonal antibody can be used as a diagnostic of a cancer. The monoclonal antibody of the invention specifically reacts with the cancer-related galactosyltransferase of the invention.
