FAST DNA polymerase (2X) MasterMix with dye

Genaxxon’s FAST DNA polymerase (2X) MasterMix with dye is the master mix of our FAST DNA polymerase (M3285) which is a robust enzyme, ideally suited for applications like genotyping and screening, amplifying with extreme speed of up to 2 seconds per 1kb, as well as high yield and consistency. FAST DNA polymerase has 5’-3’ exonuclease activity, but no 3’-5’ exonuclease (proofreading) activity. PCR products generated with this enzyme are A-tailed and can thus be cloned into TA cloning vectors. The extreme speed of Genaxxon’s FAST DNA polymerase allows the use of an extension rate of 4-8 kb/min. Genaxxon bioscience’s FAST DNA Polymerase (2X) MasterMix with dye includes all components needed for a fast PCR, except the primers. Besides this, it includes an inert red tracking dye for gel electrophoresis. Therefore, upon completion of the PCR, the reaction is ready for direct loading onto an agarose gel without the need of adding an additional loading buffer.

Example of a typical PCR protocol (graphical presentation)

* Ta is the annealing temperature (Ta should be 2°C above Tm**)

 ** Tm is the melting temperature of a primer which is defined as the temperature at which 50% of the primer bind to the complementary sequence of the target DNA. Please note: By increasing Ta above Tm, this percentage decreases, however, primers will still anneal up to a certain degree and initiate extension. Therefore, PCR would still work with a Ta of several degrees higher than the Tm but with a dramatically reduced efficiency. Hence, we recommend optimizing the Ta by performing a temperature gradient (e.g., starting at the lowest Tm or a few degrees below and increasing with 2°C increments). 

*** Largest tested amplicon size: 5kb. Please note that longer extension times may be required for targets larger than 5kb!
