Figure Lengend Snippet: Inhibition and the effect of hot-start. ( a ) Inhibition profiles of 2D9 versus AmpliTaq Gold 360 (ATaqG) in PCR. The effect of various inhibitors (SP61: bone dust, Tar, Soil, 1736; cave sediment) on polymerase activity of 2D9 and ATaqG as determined by a PCR assay in the presence of decreasing amounts of inhibitor and plotted as the average relative resistance ( n = 3, standard error) (as in Figure 4 ) of 2D9 and ATaqG with respect to ATaqG as a reference (resistance = 1). ( b ) The effect of manual hot-start on resistance of 2D9 polymerase to inhibitors tar and soil at minimal limiting amounts of inhibitor. Hot-start increases inhibitor resistance by at least a factor of two.

Article Snippet: Inhibition profiles for AmpliTaq Gold 360 DNA polymerase (Applied Biosystems) were determined using an identical PCR set-up but using AmpliTaq Gold buffer and thermocycling conditions according to manufacturer’s recommendations.

Figure Lengend Snippet: Amplification of eight copies of HPV-16 accomplished in the presence of TE buffer (lanes b, c, and d), 0.04% (final concentration [vol/vol]) NP-40 and 0.04% Tween (lanes e and f), 0.08% Tween 20 (lanes g and h), and 0.08% NP-40 (lanes i and j). The negative control is in lane a. Amplification was done with AmpliTaq Gold DNA polymerase in a model 9600 DNA thermal cycler. A 450-bp band is visible in positive reactions.

Article Snippet: Ten-microliter volumes of the detergent preparations described below were added to 90-μl volumes of a PCR master mix containing the usual components ( , ) plus eight copies of HPV-16 (kindly provided by H. zur Hausen), 5 U of AmpliTaq Gold DNA polymerase (Perkin-Elmer, Montréal, Canada), and the L1 consensus HPV primers MY09 and MY11.
