B-Bridge 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.B-Bridge Taq DNA Polymerase has both a 5 prime to 3 prime DNA polymerase and a 5 prime to 3 prime' exonuclease activity. The enzyme lacks a 3 prime to 5 prime exonuclease activity (no proofreading ability). Taq DNA Polymerase leaves an A overhang, which makes the enzyme ideal for TA cloning.Included with Taq is Tween/magnesium free 10x Ammonium Buffer.
