| Product Name | Terminal Deoxynucleotidyl Transferase (TdT) |
|---|
| Description | TdT is a template-independent DNA polymerase located in the cell nucleus which catalyses irreversible terminal addition, via polymerization, of deoxynucleotides at the 3' hydroxyl ends of oligo or polydeoxynucleotide initiators accompanied by the release of inorganic phosphate. Applications: • Oligo and DNA 3'-terminal labeling • Homopolymeric tailing of linear duplex DNA with any type of termini • TUNEL assay (in situ localization of apoptosis) • 5'-RACE Components: • Terminal Deoxynucleotidyl Transferase: 1x500U or 1x2500U • Reaction Buffer (5X): 1x0.4ml or 2x1ml 1M potassium cacodylate, pH 7.2 (25°C), 5mM CoCl2, 0.5mM DTT, 0.05% Triton X-100 Storage Buffer: 100mM potassium acetate, pH 6.8, 2mM 2-mercaptoethanol, 0.01% Triton X-100, 50% glycerol. Unit Definition: 1 unit of the enzyme iincorporates 1 nanomole of deoxythymidylate into a polynucleotide fraction in 60 minutes at 37°C. Note: Due to the presence of CoCl2, the TdT Reaction Buffer is incompatible with downstream applications |
