GoTaq® Hot Start Polymerase contains high-performance GoTaq® DNA Polymerase bound to a proprietary antibody that blocks polymerase activity. The polymerase activity is restored during the initial denaturation step when the amplification reactions are heated at 94–95°C for two minutes. This enables hot-start PCR, where polymerase activity is eliminated or minimized at temperatures below 70°C. GoTaq® Hot Start Polymerase also exhibits 5´→3´ exonuclease activity. The enzyme is supplied with a tube of 25mM MgCl₂ to optimize the magnesium concentration in your reactions.

GoTaq® Hot Start Polymerase is supplied with 5X Green GoTaq® Flexi Buffer and 5X Colorless GoTaq® Flexi Buffer. The buffers contain a compound that increases sample density so that samples sink easily into wells of an agarose gel. The green buffer also contains two dyes (yellow and blue) that separate to allow easy monitoring during electrophoresis. Use the green reaction buffer for direct-to-gel analysis after amplification and the colorless reaction buffer for amplifications where the dyes may interfere with post-amplification analysis such as fluorescence or absorbance testing.
