TdT Marker for Leukemia Diagnosis - Immunohistochemistry: Terminal Deoxynucleotidyl Transferase (TdT)

Immunohistochemistry for Terminal Deoxynucleotidyl Transferase (TdT) aims to detect this nuclear enzyme present in the nuclei of immature, primitive lymphocytes during their development in the bone marrow and thymus. TdT is a highly specific marker for lymphocytes in the early stages of differentiation.
