Simple DNA extension rate assays can be performed on real-time PCR instruments. Activity is decreased by monovalent cations, DNA dyes, and most melting temperature depressors. Rational inclusion of PCR components on the basis of their
effects on polymerase extension is likely to be useful in PCR, particularly rapid-cycle or fast PCR.
