In this report, the authors describe a murine anti-human monoclonal antibody, L3B12, which defines a pan-leukocyte cell surface antigen of approximately 180,000 m.w. Extensive screening against a variety of tissues indicates that L3B12 is sensitive and specific for leukocytes, related cells of bone marrow lineage, and their corresponding neoplasms. Unlike many lymphoid antigens that are not detectable following routine fixation and embedding, those recognized by L3B12 and related antibodies are variably preserved. L3B12 has proven useful in studying the antigen expression of normal leukocytic elements, lymphomas, and related disorders, and in enriching or depleting leukocytes from heterogeneous cell populations. From a diagnostic standpoint, L3B12 staining of tissue sections or cell suspensions is useful for distinguishing large cell lymphomas from undifferentiated carcinomas and in distinguishing lymphomas and leukemias from other small round cell tumors of childhood.
