What is Q-Bond used in the QIAGEN Fast Cycling PCR and QuantiFast Kits?

The Q-Bond Molecule, present in the PCR Buffer of the QIAGEN Fast Cycling PCR Kit and the QuantiFast Kits, dramatically increases the binding affinity of DNA polymerase to single-stranded DNA, thereby facilitating the reduction of annealing time to just a few seconds. It is a non-protein PCR component. Unfortunately, all further information on this molecule is proprietary.
