Description: Taq DNA Polymerase is a thermostable DNA polymerase that possesses a 5´→ 3´ polymerase activity (1,2,3) and a 5´ flap endonuclease activity (4,5).
Crimson Taq DNA Polymerase offers superior performance in its newly formulated PCR buffer. Crimson Taq (Mg-free) Reaction Buffer contains a density reagent, which allows direct loading of PCR products onto a gel. In addition, Crimson Taq (Mg-free) Reaction Buffer has a trace amount of a red dye, which serves as an indicator for homogenous reaction setup, a color aid in gel loading and a tracking dye which migrates at about 10 bp on a 1% TBE gel.
Source:
An E. coli strain that carries the Taq DNA Polymerase gene from Thermus aquaticus YT-1.
