A New B Cell Differentiation Antigen (BDA) on Normal and Leukemic Human B Lymphocytes That Is Distinct from Known DR (Ia-Like) Antigens

Abstract

A newly defined human B cell differentiation antigen, designated as BDA, has been defined and partially characterized. BDA is expressed on normal human B cells and lymphocytic leukemia cells at all stages of known differentiation (pre-B cells to plasma cells). It is distinct from DR (Ia-like) determinants and other known B cell surface constituents.
