Bullseye PREMIUM Taq DNA Polymerases
Store at -20°C. For in-vitro laboratory use onlyBullseye Taq DNA Polymerase is a thermostable recombinant DNA polymerase, which exhibits very high activity in primer extension and other molecular biology applications. The enzyme is isolated from Thermus aquaticus and has a molecular weight of approximately 94 kDa.
Bullseye Taq DNA Polymerase has both a 5'®3' DNA polymerase and a 5'®3' exonuclease activity. The enzyme lacks a 3'®5' exonuclease activity (no proofreading ability). Taq DNA Polymerase leaves an A¢ overhang, which makes the enzyme ideal for TA cloning.

Suggested Protocol using Taq DNA Polymerase
This protocol serves as a guideline only. Optimal reaction conditions may vary and must be individually determined.
n In some applications, MgCl2 is needed for the best results. For this reason, 25 mM MgCl2 is included with the kit.
1. Thaw 10X Mg2+ Free Standard Buffer, dNTP mix, 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.

4. Add template DNA to the individual tubes containing the master mix.
5. Program the thermal cycler according to the manufacturers instructions. For maximum yield and specificity, temperatures and cycling times should be optimized for each new template target or primer pair.
6. Place the tubes in the thermal cycler and start the reaction.

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.

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

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, produces satisfactory results. Table 2 provides the volume of 25mM MgCl2 to add to the master mix if a higher MgCl2 concentration is required.

PCR DNA Clean-up Kit
The 96-well PCR Clean-Up/DNA Extraction Kits provide a high-throughput, rapid and economical method to purify DNA fragments. Chaotropic salt is used to denature enzymes and in this condition, DNA fragments are bound by the glass fiber matrix in each well of the plate. Once the contaminants have been removed, the purified DNA is eluted by a low salt elution buffer or water. Salts, enzymes, and unincorporated nucleotides are effectively removed from reaction mixtures without toxic phenol extraction or alcohol precipitation. This entire protocol can be completed in 30-40 minutes, and the eluted DNA is ready to use in restricted digestion, ligation, PCR, and sequencing reactions.Specifications
