Characterization of T cell surface glycoproteins T1 and T3 present on all human peripheral T lymphocytes and functionally mature thymocytes

Abstract
The monoclonal antibodies, anti‐T1 and anti‐T3, both react with all human peripheral thymus‐derived lymphocytes and with 10% of thymocytes; each, however, recognizes different cell surface structures. It was determined that the target antigen of anti‐T1 is a 69000 molecular weight cell surface glycoprotein and that the T3 antigen is a 19000 mol. wt. glycoprotein.
