Terminal Deoxynucleotidyl Transferase, Recombinant, catalyzes the repetitive addition of mononucleotides to the terminal 3´-OH of a DNA initiator accompanied by the release of inorganic phosphate. Single-stranded DNA is preferred as an initiator. Polymerization is not template-dependent. The addition of 1mM Co2+(as CoCl2) in the reaction buffer allows the tailing of 3´-ends with varying degrees of efficiency.
Features - Benefits
Tails Any Type of 3´ End:The presence of 1mM CoCl2in the reaction buffer allows the tailing of any type of 3´ end (3´ and 5´ overhangs or blunt ends).
Tested for Apoptotic DNA Labeling:Each lot of enzyme is qualified for success in the procedure outlined in theDeadEnd™ Fluorometric TUNEL System Technical Bulletin#TB235.
Provided with 5X Reaction Buffer:500mM cacodylate buffer (pH 6.8 at 25°C), 5mM CoCl2, 0.5mM DTT.
