Platinum™ Taq DNA Polymerase (Invitrogen™)

Invitrogen Platinum Taq DNA Polymerase is a convenient and reliable "hot start" thermostable DNA polymerase for PCR that provides enhanced specificity over that of Taq DNA Polymerase. The "hot start" property of the enzyme is conferred by thermolabile monoclonal antibodies that render Taq DNA polymerase inactive until the initial PCR denaturation step, thus preventing the extention of nonspecifically annealed primers and improving product yield.

Using Platinum Taq DNA Polymerase
The hot-start property of Platinum Taq DNA Polymerase allows for convenient reaction assembly at room temperature. Just as with Taq DNA Polymerase, Platinum Taq DNA Polymerase has a non-template–dependent terminal transferase activity that adds a 3′ deoxyadenosine to product ends, and has a 5′→3′ exonuclease activity. PCR products generated with Platinum Taq DNA Polymerase may be used in the same downstream applications without protocol modifications. Use Platinum Taq DNA Polymerase for the amplification of DNA from complex genomic, viral, and plasmid templates, as well as in RT-PCR.

Note: For superior PCR performance, we recommend next-generation enzyme Platinum II Taq Hot-start DNA Polymerase. Platinum II Taq Hot-Start DNA Polymerase is designed for universal primer annealing and fast, easy PCR with its unique combination of innovative buffer, high-performance engineered Taq DNA polymerase, and superior hot-start technology.

Platinum™ II Hot-Start PCR Master Mix (2X) (Invitrogen™)

Invitrogen Platinum II Hot-Start PCR Master Mix (2X) offers Platinum II Taq Hot-Start DNA Polymerase premixed with Platinum II PCR buffer and dNTPs for convenient PCR setup. Platinum II Taq Hot-Start DNA Polymerase is designed for universal primer annealing and fast, easy PCR with its unique combination of innovative buffer, high-performance engineered Taq DNA polymerase, and leading hot-start technology.

Features of Platinum II Hot-Start PCR Master Mix (2X) include:
Innovative buffer—enables universal annealing temperature by isostabilizing primer-template duplex structures
Engineered Taq DNA polymerase—confers fast cycling and resistance to common inhibitors
Platinum hot-start technology—enables superior specificity, sensitivity, and yields; allows for room temperature reaction setup

Platinum II Taq Hot-Start DNA Polymerase is an engineered Taq DNA polymerase that shows increased resistance to reaction inhibitors originating from sample material or DNA purification steps. The polymerase has a higher DNA synthesis rate and delivers PCR results more than two times faster than other Taq DNA polymerases. Proprietary Platinum Taq antibodies block polymerase activity at ambient temperatures and dissociate after the initial denaturation step at 94°C. This automatic "hot start" provides increased sensitivity, specificity, and yield, while allowing reaction assembly at room temperature.

Due to the unique composition of the Platinum II PCR buffer, the annealing temperature is 60°C for most primer pairs designed following the general design rules. Isostabilizing molecules in the buffer increase primer–template duplex stability during the annealing step and contribute to enhanced specificity without the need to optimize annealing temperature for each primer pair. With Platinum II Hot-Start PCR Master Mix (2X), different PCR assays can be cycled together using the same protocol with universal primer annealing temperature and the extension step selected for the longest fragment to be amplified.

Platinum II Hot-Start PCR Master Mix (2X) is provided with the optional Platinum GC Enhancer for specific amplification and improved yields of GC-rich targets.

Use Platinum II Hot-Start PCR Master Mix (2X) for the amplification of DNA from complex genomic, viral, and plasmid templates, as well as in RT-PCR, in applications like genotyping, high-throughput PCR, or with samples of suboptimal purity.

For further streamlining of PCR workflow, we offer Platinum II Hot-Start Green PCR Master Mix (2X), which additionally contains a density reagent and two tracking dyes for direct gel loading, for even fewer pipetting steps during PCR product analysis.

AmpliTaq Gold™ 360 DNA Polymerase (Applied Biosystems™)

The Applied Biosystems® AmpliTaq Gold® 360 DNA Polymerase, when used with improved AmpliTaq Gold 360 Buffer, and the optional 360 GC Enhancer, amplifies a vast range of DNA sequence contexts. AmpliTaq Gold® 360 DNA Polymerase delivers 360° coverage for a full range of targets.
* Optimized for the broadest range of targets—from everyday to challenging
* Unmatched sensitivity, specificity, and yield
* Robust amplification of GC-rich sequences with market-leading 360 GC Enhancer
* Achieves the highest quality sequencing data

Optimized for Easy and Challenging Targets

Challenging targets include AT-rich, GC-rich, primer-dimer forming amplicons, homopolymer repeats, and amplicons that pose sequencing challenges. Amplicons that previously required specialized enzymes and reaction conditions can now be reproducibly amplified with a single reagent under standardized conditions (Figure 1). Competitive benchmarking across more than 40 amplicons distinguishes AmpliTaq Gold® 360 as the best-performing enzyme, ensuring the highest probability of success for the amplification of both everyday and challenging targets (Table 1).
As shown in Figure 1, GC-rich regions are especially poorly amplified with competitor DNA polymerases and the original AmpliTaq Gold, while AmpliTaq Gold 360 provides successful, robust amplification.

Optimized for Hot-Start PCR

AmpliTaq Gold 360 DNA Polymerase provides the same hot-start specificity as AmpliTaq Gold DNA polymerase. A high-temperature incubation step is required to activate AmpliTaq Gold DNA Polymerase, which ensures that the active enzyme is generated only at temperatures in which the DNA is fully denatured and when the primers are not annealed.
When the polymerase is added to the reaction mixture at room temperature, primer extension does not occur because the enzyme is inactivated. Any low stringency mispriming events that may have occurred will not be enzymatically extended and will not be amplified. Hence, PCR setup can be performed at room temperature without concern for extension at misprimed sites. The amount of AmpliTaq Gold 360 DNA polymerase increases in the reaction slowly with each cycle number, and specific product yield increases without buildup of nonspecific products, including primer dimers. Excellent specificity across a broad range of targets is shown in Figure 1 and is summarized in Figure 2. The exquisite specificity allows easier multiplexing and allelic discrimination.

Superior Sensitivity and Amplification Length

Compared to the original AmpliTaq Gold® DNA Polymerase, AmpliTaq Gold® 360 DNA Polymerase is purified by an additional proprietary separation process to eliminate contaminating bacterial DNA sequences from the enzyme preparation. When used with the enhanced 360 Gold Buffer, this ultra-pure enzyme, in addition to its hot-start capabilities, reduces false positive results, amplifies low-level target sequences, and promotes the amplification of a variety of templates including those from bacterial and human genomes.
AmpliTaq Gold 360 DNA Polymerase efficiently amplifies targets present at low copy number (Figure 3), even in the presence of high concentrations of complex DNA, making it especially suited for low-copy pathogen detection, and amplification of targets from degraded DNA samples. The extreme purity of the enzyme contributes to its unmatched sensitivity. AmpliTaq Gold 360 DNA Polymerase efficiently and reproducibly amplifies long (up to 5 Kb) sequences. Figure 4 demonstrates robust PCR amplification of long human and plasmid DNA.

The yield of specific product increases because reactants are not wasted in the formation of unintended products. Because AmpliTaq Gold® DNA Polymerase is a chemical hot-start enzyme, there is no worry of biological contamination.
