bovine TdT.

Antigen Background

TdT is a non-template directed DNA polymerase that catalyzes the irreversible addition of deoxynucleotides to the 3′-hydroxy groups found on the end of DNA.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide.


Reacts with the lymphoblast cell line 8402 and not with normal human peripheral lymphocytes as determined by immunohistology and flow cytometry. It is specific for terminal deoxynucleotidyl transferase as determined by ELISA with bovine TdT. Anti-TdT is a useful marker for immature and neoplastic cells frequently found in leukemic states.
