Can be optimally combined with Carl ROTH ROTI ® Pol DNA polymerases Tested for “long range PCR” DNase-, RNase- and Protease-free Free of PCR inhibitors like modified bases and tetra-pyrophosphate Adjusted to pH 8,5 for superior stability even during larger numbers of freeze-and-thaw cycles Highly efficient enzymatic fabrication Also available as ready-to-use set or mix, for contamination-free applications All Carl ROTH nucleotides are manufactured from highest-quality reagents and are most thoroughly tested for quality. This testing procedure not only includes standard-PCR but also “long range PCR”, repeated quantitative light-cycling reactions, and tests for physical stability. dITP solution ≥99 %, 100 mM solution ε 249 = 12,2 E x mmol -1 x cm -1
