The Terminator 5'-Phosphate Dependent Exonuclease include this enzyme and the 10X Terminator Reaction Buffers A and B.
Size: 40 units
Terminator™ 5´-Phosphate-Dependent Exonuclease* is a processive 5´ to ;3´ exonuclease that digests RNA that has a 5´-monophosphate end. It does not digest RNA that has a 5´-triphosphate, 5´-cap or 5´-hydroxyl group. Terminator Exonuclease is not inhibited by proteinaceous RNase inhibitors, such as RiboGuard™ RNase Inhibitor or placental ribonuclease inhibitors.
Note: Terminator™ 5´-Phosphate-Dependent Exonuclease has not been optimised for RNA-Sea applications.
