Description: The monoclonal antibody 7UNA8U6 reacts with human, mouse, and rat TdT. TdT, or terminal-deoxynucleotidyl transferase, is a 60 kDa polymerase responsible for the template-independent addition of N-nucleotides at gene segment junctions of developing lymphocytes. Expression is found in the nucleus of immature lymphocytes but not in mature lymphocytes or non-lymphoid cells. TdT plays a critical role during TCR and Ig gene rearrangement and functions to increase the diversity of the lymphocyte repertoire through the addition of N-nucleotides onto the ends of newly formed P-nucleotides. After positive selection, expression of TdT becomes decreased or absent. Expression of TdT has been shown to be present in lymphoma or lymphoblastic leukemia cells.^M

Terminal Deoxynucleotidyl Transferase (TdT) is a DNA polymerase located in the cell nucleus which catalyses the polymerization of deoxynucleotides at the 3' hydroxyl ends of oligo or polydeoxynucleotide initiators and functions without a template. TdT is considered to be a highly specific marker for the diagnosis and classification of acute lymphoblastic lymphoma/leuksemias. The determination of TdT expression is most valuable when it is different to differentiate histologically between lymphoblastic lymphoma and Burkitt's lymphoma.
