Invitrogen Platinum Taq Green Hot Start DNA Polymerase provides Platinum Taq DNA Polymerase and a 10X Green PCR Buffer. Platinum Taq DNA Polymerase is a convenient and reliable hot-start thermostable DNA polymerase for PCR that provides enhanced specificity over that of Taq DNA Polymerase. The hot start property of the enzyme is conferred by thermolabile monoclonal antibodies that render Taq DNA polymerase inactive until the initial PCR denaturation step, thus preventing the extension of nonspecifically annealed primers and improving product yield.

Platinum Taq DNA Polymerase is a recombinant Taq DNA polymerase complexed with proprietary Platinum antibodies. The antibodies dissociate during the initial PCR denaturation step and the DNA polymerase regains its full activity. Just as with Taq DNA Polymerase, Platinum Taq DNA Polymerase has a non-template-dependent terminal transferase activity that adds a 3' deoxyadenosine to product ends and has a 5' to 3' exonuclease activity.

Platinum Taq Green Hot Start DNA Polymerase is provided with Green PCR Buffer that contains a density reagent and two tracking dyes and allows for direct gel loading of PCR products. The optional KB Extender used with Platinum Taq DNA Polymerase enables more versatility in PCR assays with long or GC-rich amplicons. Use Platinum Taq Green Hot Start DNA Polymerase for the amplification of DNA from complex genomic, viral, and plasmid templates, as well as in RT-PCR.

Frequently asked questions (FAQs)

Do you have any recommendations for troubleshooting the amplification of GC-rich or problematic targets with Platinum Taq Green Hot Start DNA Polymerase?

We have the following recommendations:
- Increase the extension time from 1 min/kb to 1.5 min/kb.
- Vary total PCR cycles from 20-40; 35 cycles is typical.
- Try denaturing at 95 degrees C for 45 seconds.
- Increase the amount of template for targets >5 kb.
- Use 2.5 U of Platinum Taq for each 50 µL reaction.
- GC-rich or problematic targets work better with MgSO4 instead of MgCl2.
- For GC-rich templates, test higher annealing temperatures starting with the temperature that is equal to your primer Tm and in increments of 2 degrees C for up to six different temperatures.
- Vary the KB extender solution from 1.5 µL to 4.5 µL per 50 µL reaction.

When should the KB Extender be used that comes with the Platinum Taq Green Hot Start DNA Polymerase (Cat. Nos. 11966018, 11966026, 11966034, 11966083)?

The KB Extender enhances the amplification of GC-rich and problematic sequences, and the extension of genomic DNA targets of >5 kb. The KB Extender lowers DNA melting temperature (Tm), and the co-solvent and amplification buffer offer higher primer specificity, broader Mg concentration and annealing temperature optima, as well as improved Taq thermostabilization. Please note that primer sets that generate specific products using standard PCR buffer may not benefit from using KB Extender. Excessive use of the KB Extender may reduce yield, particularly for non-GC rich amplicons. We generally recommend varying the KB Extender solution from 1.5-4.5 µL per 50 µL reaction.
