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.

Phusion Green Hot Start II High-Fidelity DNA Polymerase (2 U/µL) (Thermo Scientific™)

Featuring an error rate 50-fold lower than that of Taq, and 6-fold lower than that of Pfu, Phusion High-Fidelity DNA Polymerase is excellent choice for cloning and other applications requiring high fidelity. Phusion DNA Polymerases offer robust performance with short protocol times, even in the presence of PCR inhibitors, and generate higher yields with lower enzyme amounts than other DNA polymerase.

With Phusion Hot Start II High-Fidelity DNA Polymerase amplification proceeds without the production of nonspecific products due to the combination of Phusion DNA Polymerase and a reversibly bound, specific Affibody ligand that inhibits DNA polymerase activity at room temperature. The Affibody ligand also inhibits the 3´→5´ exonuclease activity of the polymerase, thus preventing degradation of primers and template DNA during reaction set up. At temperatures that promote polymerase activity, the ligand is released, rendering the polymerase fully active. Phusion Hot Start II DNA Polymerase is immediately reactivated at high temperatures so it does not require a separate activation step in PCR protocols.
Phusion Green Hot Start II High-Fidelity DNA Polymerase is a combination of Phusion Hot Start II DNA Polymerase and the 5X Phusion Green Buffers. The buffers include a density reagent and two tracking dyes which do not interfere with the robust performance of Phusion Hot Start II DNA Polymerase.

Also included with this product is a 360 GC Enhancer to work through challenging GC-rich templates.

AmpliTaq Gold™ 360 Master Mix (Applied Biosystems™)

AmpliTaq Gold® 360 PCR Master Mix contains everything required for successful PCR amplification in one convenient package—all components are premixed and premeasured. AmpliTaq Gold® 360 Master Mix was designed for 360° coverage of a full range of targets. The master mix is supplied at 2X the recommended usage concentration for easy dilution when adding template and primers. Designed for convenience, the AmpliTaq Gold® 360 PCR Master Mix scales to various reaction volumes for greater application and format flexibility. The main ingredient of the master mix is AmpliTaq Gold® 360 DNA Polymerase but it also contains the world-class 360 GC Enhancer which can be added optionally for high GC–content templates. With the wide template coverage, optimization of PCR reaction conditions, is virtually eliminated with the use of AmpliTaq Gold® 360 Master Mix. Key features:

• 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
• Easy-to-use, premixed master mix

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 (see figure). 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 (see table).

Optimized for automated, hot-start PCR
AmpliTaq Gold® 360 DNA Polymerase is the key ingredient in an automated, convenient, and efficient hot-start PCR. When AmpliTaq Gold® 360 PCR Master Mix is added to the reaction mixture at room temperature, the inactive enzyme is not capable of primer extension. Any low-stringency mispriming events that may have occurred will not be enzymatically extended and subsequently amplified. An initial thermal incubation step is required for activation and ensures that active enzyme is generated only at temperatures where the DNA is fully denatured. 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 (see figure). The extreme specificity allows easier multiplexing and allelic discrimination.

Amplify low-copy amplicons and long targets
AmpliTaq Gold® 360 DNA Polymerase efficiently amplifies targets present at low copy number (see figure), 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. The figure shown demonstrates robust PCR amplification of long human and plasmid DNA.

AmpliTaq™ DNA Polymerase, LD (Low DNA) with Buffer I (Applied Biosystems™)

Applied Biosystems® AmpliTaq® DNA Polymerase, LD (Low DNA), is the same enzyme as AmpliTaq® DNA Polymerase, but is further purified through a proprietary separation process to ensure that residual bacterial DNA sequences are substantially reduced.

Manufacturing process results in highly purified enzyme with lower levels of bacterial DNA

• Minimizes non-specific PCR products when amplifying bacterial targets
• Highly purified enzyme making it particularly useful for low copy number amplifications

High-Quality
This highly purified enzyme preparation ensures that non-target, false-positive PCR products will be effectively minimized when amplifying bacterial sequences. This is especially useful for low-copy-number PCR amplifications. The enzyme is quality-control tested to verify that fewer than 10 copies of bacterial 16S ribosomal RNA gene sequences are present in a standard 2.5 unit aliquot. AmpliTaq® DNA Polymerase, LD is supplied with GeneAmp® 10X PCR Buffer I. It is also available with GeneAmp® 10X PCR Buffer II and MgCl2 Solution.

Over 20 primer pairs may be combined into a single reaction for highly specific and efficient multiplexing over a broad range of primer and template concentrations.

The Phusion U Green Multiplex PCR Master Mix contains a proprietary buffer with balanced concentrations of all PCR components eliminating the need for tedious optimization. The Green format further simplifies the workflow - it includes a density reagent and two electrophoresis tracking dyes for direct loading of PCR products on gels.

Highlights

• Specific and efficient multiplex PCR of over 20 targets up to 2.5 kb
• Excellent results with templates of suboptimal purity due to inhibitor tolerance
• Fast cycling and direct loading of PCR products on gels

Applications

• Genotyping
• Pathogen detection
• Food testing
• Analysis of genetically modified organisms
• Amplification of microsatellites

The master mix is based on Phusion U Hot Start DNA Polymerase, a high performance enzyme developed using fusion technology. Similarly to other enzymes from Phusion family, Phusion U DNA Polymerase incorporates more nucleotides per binding event than any other DNA polymerase. This allows achieving high yields of PCR products with shorter extention times and consequently reduced total protocol times. Significantly enhanced processivity also enables successful multiplex PCR on difficult targets such as GC-rich templates or templates of suboptimal purity. Being highly tolerant of many PCR inhibitors, Phusion U Multiplex PCR Master Mixes can even be used with unpurified samples such as blood or serum.

Specificity of multiplex PCR is increased by Affibody-mediated hot start mechanism. Reversibly bound Affibody ligand inhibits the polymerase at ambient temperatures preventing amplification of nonspecific products and formation of primer-dimers.
