  • Title: Use of LeuM1 monoclonal antibody for the diagnosis of Hodgkin's disease.
    Author: Memon GM, Alam SM.
    Journal: J Pak Med Assoc; 1990 Jul; 40(7):156-9. PubMed ID: 1980316.
    Abstract:
    Monoclonal antibody to LeuM1, a granulocyte-related differentiation antigen, represents a highly effective reagent for detection of diagnostic "Reed-Sternberg" cells and variants in paraffin-embedded tissues of Hodgkin's disease. The "Reed Sternberg" cell in all the cases of Hodgkin's disease except lymphocyte predominance variety revealed positive intracytoplasmic/paranuclear granular staining with LeuM1 marker. The R-S cells in lymphocyte predominance variety contain probably sialylated LeuM1 antigen. All the cases of non-Hodgkin's lymphoma and reactive lymphadenitis showed no staining with LeuM1 monoclonal antibody. Therefore this antibody represents a potentially helpful diagnostic discriminant in the assessment of Hodgkin's disease and its distinction from non-Hodgkin's lymphomas and morphologically similar reactive lymphoid lesions.
