Does dUTP in Luminaris qPCR master mix influence qPCR efficiency?

Luminaris qPCR master mixes have all dTTP substituted with dUTP. dUTP presence does not influence the reaction speed and efficiency of the master mix. 100% substitution of dTTP with dUTP facilitates an efficient clearance of the contamination from previous PCR reactions.

What enzyme is used in Luminaris qPCR Master Mixes?

Luminaris qPCR master mixes contain Hot Start Taq DNA Polymerase. This is a Taq DNA polymerase, which has been chemically modified by the addition of heat-labile groups to amino acid residues blocking enzyme activity. The Hot Start Taq DNA Polymerase has ultra low residual activity until thermally activated. Therefore reactions can be assembled at room temperature with no risk for the extension of non-specifically annealed primers or primer dimers and providing higher specificity for DNA amplification. The enzyme is activated by 10 minutes incubation at 95 degrees C.

Can I prepare a qPCR plate in advance and store it for later use when using Luminaris qPCR Master Mixes?

When using a hot start polymerase it is not critical to start reactions immediately after setup. The Hot Start Taq DNA Polymerase in Luminaris qPCR Master Mixes has ultra low residual activity until thermally activated. Therefore reactions can be assembled and stored at room temperature for up to 72 hours with no risk for the extension of non-specifically annealed primers or primer dimers.
