Taq DNA Polymerase is a thermostable recombinant DNA polymerase, which exhibits very high activity in primer extension and other molecular biology applications. The enzyme is isolated from Thermus aquaticus and has a molecular weight of approximately 94 kDa. Taq DNA Polymerase has both a 5' to 3' DNA polymerase and a 5' to 3' exonuclease activity. The enzyme lacks a 3' to 5' exonuclease activity (no proofreading ability). Taq DNA Polymerase leaves an A prime overhang, which makes the enzyme ideal for TA cloning. Glycerol free Taq is ideal for automation and free drying applications. Included with Taq are magnesium free 10x Ammonium Buffer and 10x Combination Buffer.
