Background: Identification of human T cells and subset of NK cells associated with the receptor for sheep erythocytes rosettes expressing the 45-50,000 M.W. surface antigen. Identification of human T lymphocytes in multiple stages of T cell development, including a major subset of mature peripheral T cell. Identification of CD20 on human B cells associated with approximately 10% of peripheral blood lymphocytes.
