TopTaqDNA Polymerase Enzyme (with 2.5 mM dNTPs)

TopTaq DNA Polymerase contains three binding proteins: one binding protein binds to double-stranded DNA template, preventing polymerase activity at room temperature, and the other two binding proteins bind primers, preventing primer-dimer formation. Together, these binding proteins reduce non-specific amplification. The blocking proteins are released from primers and templates during the initial denaturation. This double-blocking method has higher efficiency and specificity than antibody-based or chemically-modified hot start PCR. Template-independent "A" can be generated at the 3' end of the PCR product. PCR products can be directly cloned into T-vectors. This kit does not use Taq antibodies, reducing the risk of mammalian DNA contamination, and this kit does not use chemical modification, so a long denaturing step is not required. Genomic DNA fragments can be amplified up to 15 kb.

The suggested working concentration range for the 10X GC Enhancer provided in this kit is 0.5-5X. A final concentration of 2 mM MgSO4 is sufficient to amplify most targets. Some targets may require a higher concentration of Mg2+ For optimal results, we recommend using a 100 mM MgSO4 stock solution to prepare a titration from 2 mM to 4 mM (final concentration) in 0.25 mM increments. 0.5 µl (2.5 U) of enzyme is sufficient for a reaction vlume of 50 µl. For increased amplification, up to 1 µl (5 U) of enzyme can be used.
