Storage: 4°C for up to one month, or -20°C for long term storage.

Magnesium Chloride: In general, 1.5 mM MgCl2 is recommended; this may vary with different conditions and primer sets. Some primers/templates may require adjustments for MgCl2 concentration, which can be achieved as shown below:

Directions for use: For a 50 uL reaction, use 25 uL of the Taq Master Mix, add template, primers, and water to a final volume of 50 uL. Cycling conditions vary for different templates and primers. To start with, try 30 cycles as follows: denature at 94°C for 30 seconds, anneal around 55°C for 30 seconds, and extend at 72°C for 1 minute / kb. After the PCR cycles, extend at 72°C for another five minutes to complete the PCR. Then store the reaction at 4°C.

Bullseye PREMIUM GC Rich Optimized DNA Polymerases and Kits

General Description
Bullseye GC HS 2x Master Mix II is an all-in-one 2x master mix containing HS DNA polymerase, GC Buffer II, enhancer, dNTPs and MgCl. Simply mix GC HS 2x Master Mix II with primers,template and water and you are ready to carry out successful primer extensions. HS 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, increased sensitivity and greater yields when compared to standard DNA polymerases.

Bullseye PREMIUM PR DNA Polymerase

• Provides higher fidelity than standard Taq DNA Polymerase
• Produces blunt-ended fragments
• Processes <3 kb with extremely high fidelity

Store at -20°C. For in-vitro laboratory use only

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.

Table 1. Reaction components (master mix and template DNA)

Table 2. MgCl2 concentration in a 50 uL reaction

3. Mix the master mix thoroughly and dispense appropriate volumes into reaction tubes. Mix gently, e.g., by pipetting the master mix up and down a few times.

4. Add template DNA (0.1-0.5 mg/reaction) to the individual tubes containing the master mix.

5. Program the thermal cycler according to the manufacturer's instructions. PR is a proofreading enzyme and requires an extension time of 1-2 min/kb. For maximum yield and specificity, temperatures and cycling times should be optimized for each new template target or primer pair.

Bullseye PREMIUM HS-Taq DNA Polymerase

Store at -20°C. For in-vitro laboratory use only

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.
