PR1MA Taq DNA Polymerase 1X Master Mix

 

PR1MA DNA polymerase 1X Master Mix saves time and cost by enabling direct PCR amplification of unpurified templates. It contains a recombinant, truncated (lacks 5’ to 3’ exonuclease activity), highly thermostable DNA polymerase from the thermophilic bacterium Thermus aquaticus. The enzyme is thermostable up to 98°C for polymerase chain reaction assays and is provided as a complete reaction master mix consisting of reaction buffer, dNTPs, MgCl2, and loading dye and only requires the addition of primers and DNA template. Once PCR is complete, the reaction products can be loaded directly into an agarose gel for analysis.

  • Lacks exonuclease activity
  • Thermotolerant up to 98°C
  • Inhibitor Resistant
  • Ideal for colony PCR, genotyping, and GC-rich templates
  • Storage temperature: -20°C 

Important note: Please be sure to use the buffer provided with this product to ensure optimal results.

Bullseye PREMIUM PR DNA Polymerase is a thermostable enzyme with proofreading ability, which can be used in primer extension reactions and other molecular biology applications. PR Polymerase exhibits both 5'-3' DNA polymerase activity and 3'-5' proofreading exonuclease activity. It is recommended for applications, which require extremely high fidelity or blunt ending.


Optimal reaction conditions are achieved by using the 10x Ammonium buffer containing MgCl2 provided with the enzyme. 25 mM MgCl2 is also included separately, in case a higher MgCl2 concentration is required for a specific reaction.


Unit Definition
One unit is defined as the amount that incorporates 10 nmoles of dNTPs into acid-precipitable form in 30 minutes at 72°C under standard assay conditions.

10X Ammonium Reaction Buffer
Tris-HCl pH 8.5, (NH4)2SO4, 1% Tween20,
15mM MgCl2

PR Storage Buffer
50 mM Tris-HCl (pH 8.0), 50 mM NaCl, 0.1 mM EDTA, 1 mM DTT, 50% Glycerol, 0.1% NP40, 0.1% Tween-20.

Quality Control
Endonuclease, exonuclease and priming activities are not detected after 3 hours incubation of 1 mg of pUC19 plasmid DNA and 0.5 µg EcoR I digested lambda phage DNA at 72°C in the presence of 40 units of PR DNA Polymerase.

Suggested Protocol using PR DNA Polymerase
This protocol serves as a guideline. Optimal reaction conditions must be individually determined.


1. Thaw 10X Ammonium Buffer, dNTP mix, and primer solutions. It is important to mix the solutions completely before use to avoid localized concentrations of salts.


2. Prepare a master mix according to Table 1. The master mix typically contains all the components needed for extension except the template DNA.
The optimal MgCl2 concentration should be determined empirically but in most cases a concentration of 1.5 mM, as provided in the 1X Ammonium Buffer, will produce satisfactory results. Table 2 provides the volume of 25 mM MgCl2 to add to the master mix if a higher MgCl2 concentration is required.

General Description

Bullseye HS Taq DNA Polymerase is a modified form of Bullseye Taq DNA Polymerase, which is activated by heat treatment. A chemical moiety is attached to the enzyme at the active site, which renders the enzyme inactive at room temperature. Thus, during setup and the first ramp of thermal cycling, the enzyme is not active and misprimed primers are not extended. The result is higher specificity and greater yields when compared to standard DNA polymerases.

Once the reaction reaches optimal activating temperature, the chemical moiety is cleaved during a 15 minute heat activation step, releasing the active HS Taq DNA Polymerase into the reaction.

10X HS Buffer I

Tris-HCl, pH 8.5 (NH4)2S04, 15 mM MgCl2, 1% Tween 20.

10X HS Buffer II

An optimized buffer with a balanced ammonium/potassium concentration. May improve results with more complicated PCR reactions such as multiplex PCR.

Tris-HCl pH 8.7, Balanced KCl/(NH4)2S04, 15 mM MgCl2, 1% Tween 20.

HS Taq Storage Buffer

Enzyme is supplied in 20 mM Tris-HCl pH 8.3, 100 mM KCl, 0.1 mM EDTA, 1 mM DTT, 0.5% Tween 20®, 0.5% NP40, 50% glycerol.

Unit Definition

One unit is defined as the amount that incorporates 10 nmoles of dNTPs into acid-precipitable form in 30 minutes at 72°C under standard assay conditions.

Quality Control

Endonuclease, exonuclease and priming activities are not detected after 3 hours incubation of 1 mg of pUC19 plasmid DNA and 0.5 µg EcoR I digested lambda phage DNA at 72°C in the presence of 40 units of TEMPase DNA Polymerase.

Suggested Protocol using HS Taq DNA Polymerase

This protocol serves as a guideline. Optimal reaction conditions must be individually determined.

  • 15 mM MgCl2 is present in the 10X HS Buffer I and II. However, in some applications, more than 1.5mM MgCl2 is needed. For this reason, 25mM MgCl2 is included with the kit. Table 2 provides the volume of 25mM MgCl2 to add to the master mix if a higher MgCl2 concentration is required.

    1. Thaw 10X HS Buffer I or/and 10X HS Buffer II, dNTP mix, primer solutions. It is important to mix the solutions completely before use to avoid localized concentrations of salts.

General Description
Bullseye offers a product series specifically developed for the amplification of GC-rich DNA sequences. The Bullseye HS DNA Polymerase combined with GC Buffer I and GC Buffer II promote excellent amplification results with targets of varying degrees of GC content. Hot Start DNA Polymerase is a modified form of Bullseye Taq DNA Polymerase. A chemical moiety is attached to the enzyme at the active site, which renders the enzyme inactive at room temperature. Thus, during setup and the first ramp of thermal cycling, the enzyme is not active and misprimed primers are not extended. Once the reaction reaches optimal activating temperature, the chemical moiety is cleaved during a 10-15 minutes heat activation step, releasing the active Hot Start DNA Polymerase into the reaction. The GC Buffers in combination with Hot Start DNA Polymerase and the heat activation step result in a high success rate in amplification of DNA targets with high GC content.

Key Features

  • Amplification of multiple DNA targets with high GC content
  • High specificity, sensitivity and product yield
  • Diminished formation of non-specific product
  • Detection of low copy number targets

    Kit Components:
    HS DNA Polymerase in Storage Buffer
    5 U/ml Hot Start DNA Polymerase, 20 mM Tris-HCl pH 8.9, 100
    mM KCl, 0.1 mM EDTA, 1 mM DTT, 0.5% TweenÒ 20,

General Description

Bullseye HS Taq Polymerase, 2X Mix is a ready-to-use 2.0X master mix. Simply add primers, template, and water to successfully carry out primer extensions and other molecular biology applications.

Bullseye HS Taq Polymerase Mix, the NH4+ buffer system, dNTPs and magnesium chloride are present in HS Taq Pol Mix with HS Buffer I. Each reaction requires 25 µL of the 2.0X reaction mix. Simply add primers, template and water to a total reaction volume of 50 µL.

Bullseye" HS Taq Polymerase Mix is a modified form of Bullseye Taq DNA Polymerase, which is activated by heat treatment. A chemical moiety is attached to the enzyme at the active site, which renders the enzyme inactive at room temperature. Thus, during setup and the first ramp of thermal cycling, the enzyme is not active and misprimed primers are not extended. The result is higher specificity and greater yields when compared to standard DNA polymerases.

Bullseye" HS Taq Polymerase Mix offers several advantages. Set up time is significantly reduced. The chance of contaminating component stocks is eliminated. Reduction of reagent handling steps leads to better reproducibility. Standard tests can be set up with the confidence that results will be consistent every time.

General Description

Bullseye R-Taq DNA Polymerase is a thermostable recombinant DNA polymerase, which exhibits very high activity in primer extension and other molecular biology applications. R-Taq contains a red dye which provides easy and quick identification of reactions to which enzyme was added and allows confirmation of complete mixing. The inert dye has no effect on downstream processes. R-Taq is added directly to the reaction mix and is used in the same manner as standard Taq DNA Polymerase.

Bullseye R-Taq DNA Polymerase has both a 5'®3' DNA polymerase and a 5'®3' exonuclease activity. The enzyme lacks a 3'®5' exonuclease activity. R-Taq DNA Polymerase leaves an A-overhang, which makes the enzyme ideal for TA cloning.
