WebTerminal transferase (TdT) is a template independent polymerase that catalyzes the addition of deoxynucleotides to the 3' hydroxyl terminus of DNA molecules. Protruding, recessed or blunt-ended double or single-stranded DNA molecules serve as a substrate for TdT. The 58.3 kDa enzyme does not have 5' or 3' exonuclease activity. WebTdT (terminal deoxynucleotidyl transferase) is a DNA polymerase present in precursor T cells and thymocytes, as well as a subset of B lymphoblasts. Anti-TdT antibodies are routinely used for the detection of B and T lymphoblastic leukemias/lymphomas plus lymphoid blast transformation in chronic myelogenous leukemia.
