DNTT/TDT protein (recombinant bovine)

Endotoxin level: < 10 EU/mg of the protein as determined by the LAL method. Protein function: Template-independent DNA polymerase which catalyzes the random addition of deoxynucleoside 5'-triphosphate to the 3'-end of a DNA initiator (PubMed:3755527). One of the in vivo functions of this enzyme is the addition of nucleotides at the junction (N region) of rearranged Ig heavy chain and T-cell receptor gene segments during the maturation of B- and T-cells.
