Description
ExcelTaq™ Klen-Taq DNA Polymerase 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 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 Taq DNA polymerase. The ExcelTaq Klen-Taq DNA Polymerase is ideal for DNA amplifications 0.5-5 kb in length on genomic DNA, and up to 10 kb on less complex templates.
Features
5"→3" DNA polymerase activity
3"→5" exonuclease activity (proofreading)
Thermo-stable up to 98°C during PCR denaturing step

General Terms and Conditions / Service Policies
Does ExcelTaq™ Klen-Taq DNA Polymerase (TK1000) product have chemical modification or biological modification?
It is without any modification. Moreover, the proof-reading activity of Klen-taq products is thrice that of a normal Taq DNA polymerase.
Is ExcelTaq™ Klen-Taq DNA Polymerase (TK1000) a blended enzyme mix?
Klen-Taq DNA polymerase (TK1000) is blended KlenTaq DNA polymerse and a small amount proofreading enzyme.
What is the end structure of PCR products generated by ExcelTaq™ Klen-Taq DNA Polymerase (TK1000)?
Since ExcelTaq™ Klen-Taq DNA polymerase (TK1000) is blended KlenTaq-1 DNA polymerse and a small amount proofreading enzyme, the end structure of PCR products generated by ExcelTaq™ Klen-Taq DNA Polymerase will be mixture of 3’-dA overhangs and blunt ends.
