Cycle Numbers

Fig. 4 Quantitative dynamics in PCR amplicon generation. After a certain number of PCR cycles, detectable amplicon amounts are generated (with the target amounts used here, after about 18 and 24 cycles, respectively). These amounts are amplified logarithmically for only about five subsequent PCR cycles, and, finally, a static plateau phase is reached (at about 26 and 32 cycles, respectively).

For GC-rich targets, consider replacing dGTP by base analogs with reduced Tm, such as deaza-dGTP or dITP. Increase the amount of template DNA per reaction by increments of 50 ng. Increase the amount of enzyme (up to 5 U/50 mL). Increase the magnesium ions (up to 3.5 mM).

Getting Started With Dumbbells

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
