Benefits of high fidelity Platinum SuperFi II DNA Polymerase
High fidelity
Platinum SuperFi II DNA Polymerase preserves DNA sequence accuracy with its extremely low error rate. Using next-generation sequencing, the relative fidelity of Platinum SuperFi II DNA polymerase was calculated to be >300x that of Taq DNA polymerase (Figure 1).
Figure 1. Fidelity comparison across commercially available enzymes relative to Taq enzyme. A 3.9 kb sequence was amplified by PCR using different DNA polymerases, and the resulting PCR amplicons were then fragmented with a MuA transposase. Unique molecular identifiers (UMI), which consist of 12 random nucleotides, were introduced during fragmentation to individually tag each product. After next-generation sequencing, reads were aligned to the correct sequence, grouped by UMI families, and errors were called. Errors were identified only if they were present in all reads in the UMI family; otherwise, they were discarded as sequencing errors. The polymerase fidelities were normalized to the Taq DNA polymerase.
60°C primer annealing
The innovative buffer formulation of Platinum SuperFi II buffer enables annealing of primers at 60°C regardless of their sequences (Figure 2). The buffer also allows successful amplification when calculated Tms are used in the annealing step (data not shown). This universal annealing feature allows co-cycling assays (Figure 3 and 4).
Figure 2.Platinum SuperFi II DNA Polymerase produces PCR products with high specificity and yield following the universal annealing temperature at 60°C. Primer sets of varying annealing temperature were used to amplify 12 targets from 50 ng of human genomic DNA at 60°C annealing temperature. The molecular weight marker is Invitrogen TrackIt 1 Kb Plus DNA Ladder. The annealing temperatures stated were calculated using the Tm calculator for Platinum SuperFi DNA Polymerase.
Figure 3. Time saving and assay co-cycling enabled by universal PCR protocol. PCR assays using conventional PCR reagents require specific protocols for amplification of each DNA fragment because of the different primer annealing temperatures and extension steps; therefore, multiple targets often cannot be amplified together in the same PCR run. With Platinum SuperFi II DNA Polymerase, different PCR assays can be cycled together using one protocol with a universal primer annealing temperature and the extension time selected for the longest fragment to be amplified (Figure 4).
Figure 4. Platinum SuperFi II DNA Polymerase enables cycling of shorter and longer amplicons together. 0.7 kb, 2.0 kb, 4.8 kb, and 14 kb fragments were amplified from 100 ng of human genomic DNA using the same protocol for all four targets: 98°C denaturation for 10 sec, 60°C annealing for 10 sec, 72°C extension for 7 min. The extension time was based on length of the longest target.
Direct gel loading
Platinum SuperFi II Green PCR Master Mix offers the convenience of direct gel loading of PCR products, eliminating tedious steps of dye addition to PCR samples, and helping reduce pipetting errors. The green buffer (Figure 5) is compatible with downstream applications including DNA sequencing, ligation, and restriction digestion.
Figure 5. The green master mix format for loading PCR products directly to a gel for analysis. The master mix of Platinum SuperFi II DNA Polymerase is available in a green buffer format that contains a density reagent and two tracking dyes. DNA migration is easily tracked with two dyes (blue and yellow) that are readily visible during electrophoresis (the lanes for 5 and 15 min in the figure to the right).
