Description
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 in 5´ protruding ends with labeled or unlabeled dNTPs or for the generation of blunt ends from DNA molecules with 3´ overhangs or in vitro mutagenesis. The enzyme is provided with 10X Reaction Buffer: 250mM Tris-acetate (pH 7.7), 1M potassium acetate, 100mM magnesium acetate and 10mM DTT.
