Worthington CX and CXR Series Cryogenic Shippers

Pfu DNA Polymerase 
Pfu DNA polymerase is a heat stable DNA polymerase which has 5' 3' DNA polymerase and 3' 5' exonuclease (proofreading) activities. Pfu DNA polymerase retains the high fidelity, sensitivity and processivity with an error rate six-fold lower than Taq DNA polymerase, and significantly lower than the error rates of most other proofreading enzymes or DNA polymerase mixtures (1). This product is supplied with the unique Intact Genomics 10x PCR reaction buffer, containing MgCl2, which produces a final Mg2+ concentration of 1.5 mM, and 5X Magic Enhancer that enables efficient amplification of GC rich templates up to 84%. The physical purity of this enzyme is 98% as assessed by SDS-PAGE with Coomassie® blue staining.

Quality Control 
Quality control is performed following the production of each new lot of product to ensure that it meets the quality standards and specifications designated for the product. Each lot is repeatedly compared side-by-side with leading competitors to ensure our products outperform the competitor before product launching.

Protocol
1. Thaw 10x PCR Buffer, dNTP mix, primer solutions, 5x Magic Enhancer (if required) and mix thoroughly before use. 
2. Prepare a reaction mix according to the following table: The reaction mix typically contains all the components needed for PCR except the template DNA.

3. Mix the reaction mixture thoroughly.
4. Add template DNA to the individual PCR tubes containing the reaction mixture. 
5. Program the thermal cycler according to the manufacturerâs instructions. A typical PCR cycling program is outlined in the following table.
