Table 3. Relative quantitation of known concentrations of β-actin plasmid and cDNA.

Sample	Dilution	R0	Calculated dilution
β-Actin plasmid	1 000 000 copies	4.063 × 10–7	1.000
	100 000 copies	4.386 × 10–8	0.108
	10 000 copies	3.299 × 10–9	0.008
	1000 copies	2.620 × 10–10	0.001
β-Actin cDNA	1	8.805 × 10–8	1.000
	0.1	9.200 × 10–9	0.104
	0.01	8.618 × 10–10	0.010

Dilutions are calculated from the R₀ of each dilution as a fraction of the R₀ of the undiluted sample.
