IG™ Taq DNA Polymerase 2x Premix with Dye is a thermostable DNA polymerase that possesses a 5´→3´ polymerase activity (1, 2) and a 5´ flap endonuclease activity (3, 4). Ideal for primary extension reaction with DNA fragments having dA overhang on 3’ ends.

IG™ Taq DNA Polymerase 2x Premix with Dye is ready to use, containing Taq DNA Polymerase, dNTPs, MgCl2, and stabilizers. It has been optimized for routine PCR applications.

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