An highly processive, recombinant (from E.coli strain), thermostable DNA with a very high efficiency of 5’- 3’ polymerase activity and 3´- 5’ exonuclease (non-proofreading) activity. Xtra Taq Pol catalyzes the addition of mononucleotide units to the 3’-end of a primer chain, leading to the formation of DNA products that have 3’-overhanging A nucleotides (thus can be used in TA cloning). This enzyme remains funtional even after prolonged incubation steps at 95°C. The enzyme is supplied at 5U/μl and comes with 5X XtraWhite new buffer.
5X XtraWhite is a Genespin proprietary formulation, developed for standard and/or high-fidelity amplification of high-GC (>75%) templates. The buffer contains 7.5mM magnesium, PCR enhancers and thickening agents (vortex thoroughly prior to use) and is supplied with 1ml of 6X Orange Loading Dye.
The Orange G dye migrates at the same rate as a duplex DNA fragment of approximately 50 Kbp and does not interfere with DNA migration when it is used as a loading dye for agarose gel electrophoresis.
