Platinum® Taq Technology

Platinum® Taq DNA Polymerase is a recombinant Taq DNA polymerase complexed with a proprietary antibody that inhibits polymerase activity at ambient temperatures. Due to specific binding of the inhibitor, Platinum® Taq DNA Polymerase is provided in an inactive form. The DNA polymerase is then activated in a temperature-dependent manner (at 94ºC) during the start of PCR. Once dissociated from the inhibitor, the Taq DNA polymerase regains its full activity.

More Versatility for PCR products up to 10 kb

Use Platinum® Taq DNA Polymerase for expected PCR products up to 10 kb.  The optional KB Extender gives more versatility to the Platinum® Taq DNA polymerase in PCR assays. 

PCR Products

Panel A.  A 4.1-kb region of genomic target was amplified from 200-400 ng K562 genomic DNA without KB Extender (Lanes 1-2), with KB Extender at 2% final concentration (Lanes 3-4) using Platinum® Taq DNA Polymerase; the same products amplified with Competitor DNA Polymerase (Lanes 6-7).  Each reaction was performed in duplicate.

Panel B.  A 10-kb region of genomic target was amplified from 200-400 ng K562 genomic DNA without KB Extender (Lanes 1-2), with KB Extender at 2% final concentration (Lanes 3-4) using Platinum® Taq DNA Polymerase; the same products amplified with Competitor DNA Polymerase (Lanes 6-7).  Each reaction was performed in duplicate. 

Broader Magnesium Range

A 2.8-kb region of the human β-globin gene was amplified from 100 ng of human genomic DNA.

Using human genomic DNA, the amplification of a 2.8 kb region was evaluated at 1.0, 1.4, 1.8, 2.2, 2.6, and 3.0 mM magnesium (Lanes 1-6, respectively).
