  • Methods for diagnosis of low grade astrocytoma
    Patent number: 7279292
    Abstract: A method for identifying low grade astrocytoma cells in a sample is provided, wherein the method distinguishes between low grade astrocytoma cells and normal astrocytes, thus permitting early diagnosis of astrocytoma. The method uses antibody directed against J1-31 to test astrocytes in the sample for the presence or absence of J1-31 polypeptide, the low grade astrocytoma cells being characterized by the absence of J1-31 while normal astrocytes are characterized by the presence of J1-31.

  • Luminal epithelial antigen
    Patent number: 5851830
    Abstract: A cell-surface glycoprotein, termed luminal epithelial antigen, having a molecular weight of 135 Kd and which is present in normal mammary epithelial cell lines but not in malignant epithelial cell lines. A monoclonal antibody directed against said luminal epithelial antigen. Use of the monoclonal antibody in a diagnostic assay for the early identification of patients with high risk of developing breast cancer and in a prognostic assay for the prediction of recurrence of breast cancer in patients.
