T4 DNA Polymerase catalyzes the 5´→3´ synthesis of DNA from a primed single-stranded DNA template. Although possessing a potent 3´→5´ proofreading exonuclease, T4 DNA Polymerase contains no 5´→3´ exonuclease activity. T4 DNA Polymerase can be used to fill 5´ protruding ends with labeled or unlabeled dNTPs or for the generation of blunt ends from DNA molecules with 3´ overhangs.
Features - Benefits
High Fidelity:T4 DNA Polymerase is the enzyme of choice for applications where misincorporation is a concern.
Flexible:T4 DNA Polymerase may be used in a variety of molecular applications. Active in many Promega 1X restriction enzyme buffers.
May Be Heat-Inactivated:T4 DNA Polymerase is inactivated by heating at 75°C for 10 minutes.
Provided with 10X Reaction Buffer:250mM Tris-acetate (pH 7.7), 1M potassium acetate, 100mM magnesium acetate and 10mM DTT.
