For new users a serial dilution of the sample may be necessary. An example for creating 1, 10 and 100 ng/rxn follows: Determine the DNA concentration in the sample by measuring absorbance at A260 or by using a dsDNA quantification kit such as Quant-iT DNA Assay Kits (Molecular Probes #Q33120 or #Q33130) or PicoGreen (Molecular Probes #P7589).

The preferred type of calculator for AP Chemistry is the Texas Instruments® TI-30. It’s inexpensive (about $10 at Wal-Mart or Office Max/Depot), yet powerful enough to handle anything you’ll encounter in AP Chemistry or Physics. Beware of the so-called “algebraic” calculators like the two-line TI-34 and larger Casio® calculators; they ...
