ABSTRACT

Immunophenotyping of lymphohematopoetic cells and malignancies is a widely accepted procedure and is routinely utilized by hematopathologists in the diagnosis of leukemia, lymphoma, and other hematopoietic disorders [1-5]. There are perhaps more monoclonal antibodies (MoAb) that have been developed against lymphoreticular antigens than in any other area of diagnostic pathology. The easy accessibility to large numbers of normal and malignant cells from the blood, bone marrow, and lymph nodes that can potentially be converted into long-term cell cultures has obviously led to this profusion of henlatologic MoAb.
