Robust Amplification with Direct-to-Gel Convenience
GoTaq® DNA Polymerase is a proprietary formulation of Taq DNA polymerase that gives robust amplification equal to and, in some cases, superior to that of standard Taq.
The 5X GoTaq® Green and Colorless Reaction Buffers supplied with GoTaq® DNA Polymerase contain MgCl2 at a concentration of 7.5mM for a final concentration of 1.5mM in the 1X reaction.
The 5X Green and 5X Colorless Reaction Buffers allow you to go directly from thermal cycler to gel analysis. These 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. The blue dye comigrates with 3–5kb DNA fragments in a 1% agarose gel. The yellow dye migrates ahead of primers (<50bp). Use the green reaction buffer for direct-to-gel analysis after amplification and the colorless reaction buffer for post-amplification analysis by fluorescence or absorbance without prior DNA purification. PCR enhancers, such as betaine and DMSO, have no effect on the color or characteristics of the GoTaq® Green Reaction Buffer.
