Detection of prostate and other cancers by assaying for cancer-specific antigens having linked oligosaccharides which are at least triantennary

摘要

A process for assaying for cancer of the prostate, comprising assaying a sample derived from a human for prostate specific antigen having a linked oligosaccharide which is at least triantennary. The assay may employ a binding molecule which binds to oligosaccharides that are at least triantennary, but does not bind to oligosaccharides that are monoantennary or diantennary. Such binding molecule may be a lectin such as PHA-L or an antibody to an oligosaccharide that is at least triantennary.
