TK1000 ExcelTaq Klen-Taq DNA Polymerase, Great For Mouse Genotyping, Colony Screening. 5 Units/ul, 500 Units/Vial

ExcelTaq Klen-Taq DNA Polymerase (Cat# TK1000) is a specially blended enzyme mix containing KlenTaq-1 DNA polymerase (a 5’-exo-minus, N-terminal deletion of Taq DNA polymerase) and a small amount of a proofreading high fidelity DNA polymerase. This unique blending helps to improve the fidelity, yield and processivity of the resultant PCR process. The Klen-Taq is also highly robust, showing high tolerance of varying concentration of Mg2+; it is highly thermostable and has four times the fidelity compared to regular Taq DNA polymerase. The ExcelTaq Klen-Taq DNA Polymerase is ideal for DNA amplifications 0.5-5 kb in length on mouse, rat, plant genomic DNA, and up to 10 kb on less complex templates, such E coli bacterial genomic DNA, plasmid DNA, Yeast genomic DNA. If you have amplification issues with regular Taq DNA polymerase try our special formula ExcelTaq Klen-Taq DNA Polymerase.


• 5’→3′ DNA polymerase activity
• 3’→5′ exonuclease activity (proofreading)
• Thermo-stable up to 98°C during PCR denaturing step
• 4× fidelity as compared to Taq DNA polymerase
• Robust PCR performance, resistance to variance in PCR condition
