PrimeSTAR HS DNA Polymerase with GC Buffer is designed for high-fidelity PCR amplification of GC-rich templates (75% or greater GC content) and is based on our unique, high-fidelity PCR polymerase, PrimeSTAR HS DNA Polymerase. The GC buffer supplied with PrimeSTAR HS facilitates robust, efficient, and accurate extension through even highly GC-rich template regions. It offers both maximal accuracy and better amplification efficiency of high-GC templates than regular Taq polymerase. A dNTP mixture is also included in the kit.
