Background of DNTT / TDT antibody

Terminal Deoxynucleotidyl Transferase (TdT). 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. The Terminal Deoxynucleotidyl Transferase (TdT) enzyme involved in DNA polymerization and is localized in the nucleus of several hematopoeitic cells such as prothymocytes, precursor T and a subset of B cells. The TdT protein is a 58 kDa nuclear protein. The expression of TdT has been known as a nuclear maker for the hemopeotic cells for many years (1). The conspicuous absence of expression and activity of TdT clearly distinguishes B cell development in the fetus from that in adult bone marrow. The TdT is expressed in most of cases of acute lymphatic leukemia (ALL), and non Hodgkinson lymphoma (NHL), in a subset of chronic and acute myeloid leukemia (CML and AML), acute non-lymphocytic leukemia (ANLL; 1, 2). Detection of nuclear expression of TdT is a valuable method for detection of various type of leukemia and monitoring minimal residual leukemic cells. The DNA polymerase, TdT, is involved in the rearrangement of the T-cell receptor genes in early thymocytes and in rearrangement of of the immunoglobulin genes during B-cell development. These rearrangements of the T-cell receptor genes and the immunoglobulin genes are performed in the nucleus and are lost upon maturation of the immune cells. Detection of TdT by flow cytometry and by IHC can be useful in detecting a small percentage of leukemic cells, in cases such as minimal residual T-cell acute lymphoblastic leukemia (3). Other antibodies that are used to detect residual T-cell ALL are combination of Anti-TdT with CD1a, CD2, CD5 and CD7 antibodies. The sensitivity of detecting smaller percentage of cell expressing TdT can be enhanced by double or triple staining with Anti-TdT and a combination of anti-CD antibodies. Antibodies used for double staining of AML cells are combination of Anti-TdT and Anti-HLA-DR, CD13, CD33, CD34 and CD45 antibodies.
