Intact Genomics Taq DNA Polymerase with Dye is a thermostable DNA polymerase that possesses a 5´→3´ polymerase activity (1, 2) and a 5´ flap endonuclease activity (3, 4). This product is supplied with 10x PCR reaction buffer, containing MgCl2, which produces a final Mg2+ concentration of 1.5 mM. Ideal for primary extension reaction with DNA fragments having dA overhang on 3’ ends.

The physical purity of this enzyme is ≥98% as assessed by SDS-PAGE with Coomassie® blue staining.
