β1–6 branching of asparagine-linked oligosaccharides was also detected in GnT-V-positive endometrial cancer cells by leukoagglutinating phytohaemagglutinin (L4-PHA) staining, and the molecular size of the major glycoproteins recognised by L4-PHA was approximately 60–200 kDa by lectin blot analysis. The gene discussed is MGAT5; the disease is endometrial cancer.
