The second generation of GoTaq products, GoTaq G2 Flexi DNA Polymerase reliably amplifies a wide range of PCR templates and provides high-performing results due to improved manufacturing processes, increased reliability and consistency. GoTaq G2 Flexi DNA Polymerase is supplied with 5X Green GoTaq Flexi Buffer and 5X Colorless GoTaq Flexi Buffer and 25mM MgCl2. The GoTaq G2 Flexi DNA Polymerases are supplied in a proprietary formulation containing 50% glycerol with buffers designed for enhanced amplification. The enzyme is a full-length form of Taq DNA polymerase that exhibits 5'-->3' exonuclease activity. The 5X Green GoTaq Reaction and Flexi Buffers contain two dyes (blue and yellow) that separate during electrophoresis to indicate migration progress. The colorless buffer is used when direct fluorescence or absorbance readings are required without prior purification of the amplified DNA from the PCR.
