Application

GC-RICH PCR system has been used in semi‐quantitative analysis, genotyping and retrieval and cloning of high-GC content sequence of candidate gene.

The GC-RICH PCR System, a blend of Taq DNA polymerase and a proofreading polymerase, enables amplification of templates that are difficult or impossible to amplify with other polymerases and other blends of polymerases. The enhanced processivity of the blend and the unique GC-RICH Resolution Solution combine to deliver superb performance – especially from problematic templates.The GC-RICH PCR System may also be used in standard PCR applications, providing improved results (higher yield, higher accuracy) over Taq DNA polymerase alone.Advantages of the GC-Rich PCR System:Ease access to difficult templates, including GC-rich targets and repetitive sequences.Reagents, the GC-RICH Resolution Solution and PCR Grade Water are provided.Amplify DNA fragments up to 5 kb.

Features and Benefits

The GC-RICH PCR System is a blend of Taq DNA Polymerase and a proofreading polymerase for amplifying longer nucleic acid fragments. The GC-Rich Solution provides an solution to enable amplification of all kind of difficult PCR products.When using the supplied magnesium-containing buffer, the final MgCl2 concentration is 1.5 mM.

Blend of Taq DNA Polymerase and a proofreading polymerase amplifies difficult templates. Enhanced processivity and the unique GC-RICH Resolution Solution deliver superior performance. PCR Difficult templates up to 5 kbUse the GC-Rich PCR System, dNTPack with ready-to-use PCR Nucleotide Mix.

General description

The GC-RICH PCR System is composed of an enzyme blend of thermostable Taq DNA Polymerase and Tgo DNA Polymerase, a thermostable enzyme with a proofreading (3′-5′ exonuclease) activity. This polymerase mixture by itself outperforms Taq DNA Polymerase in respect to yields, fidelity and specificity beside the possibility to amplify fragments up to 5 kb in length. The GC-RICH PCR Reaction buffer in combination with the separately included GC-RICH resolution solution allows to amplify difficult templates like GC-rich targets very efficiently. TA cloning is recommended. The enzyme blend produces more blunt-ended fragments than Taq DNA Polymerase. The majority of products have single A overhangs. Use 2 U for a standard 50 µl PCR.Contents GC-RICH Enzyme Mix , in storage buffer GC-RICH Reaction Buffer, 5x concentrated, with 7.5 mM MgCl2 and DMSO GC-RICH Resolution Solution, 5 M MgCl2 Stock Solution, 25 mM Water, PCR Grade
