TDT Protein, Human (His)

TDT protein, a template-independent DNA polymerase, non-specifically adds deoxynucleoside 5'-triphosphates to the 3'-end of a DNA initiator. It crucially contributes to in vivo processes, particularly adding nucleotides at the junction (N region) of rearranged Ig heavy chain and T-cell receptor gene segments during B- and T-cell maturation. TDT Protein, Human (His) is the recombinant human-derived TDT protein, expressed by E. coli , with N-6*His labeled tag.

The TDT protein is a template-independent DNA polymerase that carries out the non-specific addition of deoxynucleoside 5'-triphosphate to the 3'-end of a DNA initiator. One of its important roles in vivo is adding nucleotides at the junction (N region) of rearranged Ig heavy chain and T-cell receptor gene segments during the maturation process of B- and T-cells.

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
