TaqTrac kTM Sequencing System The TaqTrackTM sequencing system takes advantage of the intrinsic properties of the thermostable Taq DNA polymerase. As a sequencing enzyme, kq DNA polymerase exhibits consistent band intensity and low background which contributes to more reliable sequence interpretation. The higher reaction temperature of the system (70.9OOC) decreases the secondary structure of the DNA templates and facilitates polymerization through highly structured regions, This system is useful for sequencing a wide variety of templates including lambda DNA, amplified DNA, GC-rich templates, palindromic-rich templates, and long poly(A) tatls.
